MOME2 The authors of (1972Re08) used measurements of the quadrupole interaction constant for D{-2} and HD molecules to calculate the deuteron quadrupole moment. Errors in the original value (0.2875 {I20} E-26 cm{+2}) were corrected in an erratum to yield the presently accepted value 0.2860 {I15} E-26 cm{+2}. For other values in the literature, see Table 1 of (1972Re08). See (1979Bi14) who confirm (1973Re08) based on improved computation techniques. See (1993Ha33) who cite 0.2859 {I3} E-26 cm{+2} based on (1979Bi14), however this value does not appear in the text of (1979Bi14).

$E{-res}({+3}H+4n)=1.3 MeV {I4} is the weighted average of 0.73 MeV {I+58-47} (2022Ca10), 0.57 MeV {I+42-21} (2008Ca22), 1.8 MeV {I5} (2020Be01), and 2.2 MeV {I5} (2021Mu04). 
E$The missing mass spectra of (2020Be01, 2021Mu04) are more easily understood than those of (2007Ca47, 2008Ca22, 2022Ca10). The former spectra show clear evidence of the ground and excited states of {+7}H, which are accounted for in the analysis of (2020Be01, 2021Mu04). However, the missing mass spectrum displayed on Fig. 3 of (2022Ca10) shows two wide peaks corresponding to the production of {+7}H from the ({+8}He,{+3}He) reactions on {+19}F and {+12}C targets. These two peaks are |J5 MeV wide at FWHM (for the case of {+19}F({+8}He,{+3}He)) and several MeV wide at FWHM (related to the {+12}C contribution). Such a wide range may already include at least the first excited state of {+7}H. So, it is unclear (a) why (2022Ca10) did not consider any excited states, and (b) how the interplay between the production of the {+7}H{-g.s.} and potential excited states were deconstructed from the detector response function. Therefore, even though the E{-res}({+3}H+4n) is computed from the weighted average of the results of (2020Be01, 2021Mu04, 2008Ca22, 2022Ca10), the evaluator has a preference for the analysis and results of (2020Be01, 2021Mu04). 
E$Using E{-res}=1.3 MeV {I4} and assuming the observed resonance is the {+7}H ground state, the {+7}H mass excess is |DM=48.5 MeV {I4}; this compares with |DM=49.135 MeV {I1004} given in 2021Wa16. 
T$ See also the |G=0.18 MeV {I+47-16} measured in (2022Ca10), |G=0.09 MeV {I+94-6} measured in (2007Ca47, 2008Ca22), theoretical estimation of |G|<1 keV in (2011Gr13), and theoretical estimation of |G|?0.1 MeV in (2021Li62). 
J$From L=0 in a DWBA fit to the measured angular distribution of the {+19}F({+8}He,{+20}Ne){+7}H transfer reaction data from (2022Ca10). The L=0 is inferred since the best fit for the DWBA calculation assumes that {+20}Ne is in its ground state, and that the proton is removed from the ground state of {+8}He (2022Ca10). 
$The decay mode is most likely to {+3}H+{+4}n, but the direct emission of a tetraneutron from the {+7}H{-g.s.} is not yet experimentally observed. The preliminary analysis of (2021Hu28) seems to be suggestive of this decay mode.

$E{-res}({+3}H+4n)=0.73 MeV {I+58-47} from (2022Ca10) 
E$The missing mass spectrum displayed on Fig. 3 of (2022Ca10) shows two wide peaks corresponding to the production of {+7}H from the ({+8}He,{+3}He) reactions on the {+19}F and {+12}C targets. These peaks are respectively |J5 MeV and several MeV wide at FWHM and are attributed to the contributions from {+19}F and {+12}C, respectively. Such a wide range may already include at least the first excited state of {+7}H, which is not considered in (2022Ca10). It is unclear how (2022Ca10) extracted the energy and width of the {+7}H{-g.s.} from the detector response function, and why they did not include any potential excited states.

$The spectroscopic factor deduced from normalizing the DWBA cross section to the experimental angular distribution of the {+19}F({+8}He, {+20}Ne){+7}H reaction was observed (2022Ca10) to vary between 4.5 {I28} and 12.7 {I61}, depending on the nuclear density used for {+8}He in the DWBA calculation.

T$the raw measured value of T{-1/2}=838.57 ms {I36} is dominated by statistical uncertainty. A systematic error correction of -0.17 ms {I0} accounts for "pile-up" losses in the decay spectrum in the early period of high-rate counting. Furthermore, a systematic uncertainty of 0.04 ms is added in quadrature to the statistical uncertainty. After these corrections, the resulting value is T{-1/2}=838.40 ms {I36}. 
The present result improves on the precison of {+8}Li half-life value by a factor of 2.5. 
T$the world average of "modern" results [from present, 1990Sa16, 2003Wi17] yields T{-1/2}=838.75 ms {I32}. A higher value of 844.0 ms 7 from 1966Cl02 is omitted.

T The {+7}Be half-life has been observed to vary depending on the chemical form of the {+7}Be. Some of these measured variations are: 
$ Reference Forms compared (|D|lx1.0e{+4})/|l 
$ 1949Se20 Be - BeO 1.5 (9) 
$ 1953Kr16 Be - BeO 1.3 (5) 
$ BeO- BeF{-2} 6.1 (6) 
$ Be - BeF{-2} 7.4 (5) 
$ 1956Bo36 Be - BeF{-2} 12 (1) 
$ 1970Jo21 BeO- BeF{-2} 11.3 (6) 
$ BeO- BeBr{-2} 14.7 (6) 
$ BeO- Be{-4}O(CH{-3}COO){-6} -7.2 (6) 
$ BeO- Be(C{-5}H{-5}){-2} 8.0 (7) 
$ BeO- Be(OH{-2}){-4} -3.7 (8) 
$ BeF{-2}- Be{-4}O(CH{-3}COO){-6} -18.5 (8) 
$ Be(C{-5}H{-5}){-2}- Be(OH{-2}){-4} -11.7 (11) 
$ 1999Hu20 BeO - Be(OH){-2} -149. 
$ BeO - Be{+2+}(OH{-2}){-4} -98. 
$ 1992Ra12 Be in Au - Be in Al{-2}O{-3} 72. (7) 
Excluding the much larger changes reported by 1999Hu20 and 1999Ra12, these measured changes range from 0.01% to 0.2%, or from 0.005 to 0.10 days, or 0.08 day if the organic compounds are also omitted. 
T Adopted 53.22 d 6 from Limitation of Relative Statistical Weight (LRSW) (1985ZiZY, 1992Ra09) analysis of 53 d {I2} (1940hi01), 52.93 d {I22} (1949Se20), 53.61 d {I17} (1953Kr16), 53.0 d {I4} (1956Bo36), 53.5 d {I2} (1957Wr37), 53.1 d {I3} (1965En01), 53.52 d {I10} (1970Jo21), 53.0 d {I3} (1974Cr05), 53.17 d {I2} (1975La16), 53.16 d {I1} (1982ChZF), 53.284 d {I4} (1982RuZV), and 53.12 d {I7} (1996Ja10). In this analysis the uncertainty of 1982RuZV value was increased from 0.004 to 0.0088 so that its relative weight was reduced from 83% to 50%. The weighted average of these values is 53.225 with an internal uncertainty of 0.006, a reduced-|h{+2} of 10.5, and an external uncertainty of 0.020. This uncertainty increased by the LRSW method to 0.06 so that the most precise value of 53.284 is included; this uncertainty also includes the next most precise value of 53.16. 
T The adopted half-life is dominated by the values of 1975La16, 1982ChZF, and 1982RuZV which contribute 10%, 39%, and 50% of the relative weight, respectively. The values of 1982ChZF and 1982RuZV differ by |? 10 |s and contribute 3.8 and 4.1 to the reduced-|h{+2} value of 10.5. Since these three values differ by 0.12 days and the chemical forms in the latter two cases are not known, the chemical variation data in the above table suggest that some of this difference may be due to chemical affects. This suggests that the adopted uncertainty of 0.06 days is reasonable for general use. 
T Values not used are: 54.5 d (J. F. Bonner, Jr., AEC report AECU-107 as quoted in 1953Kr16, no uncertainty); and 54.3 d {I5} (Bouchez, Daudel, Daudel, and Muxart, J. Phys. et Radium 8 (1947) 336 as quoted in 1953Kr16, replaced by value of 1956Bo36); and 53.694 d {I6}, 53.416 d {I6}, and 54.226 d {I6} (1999Hu20). The values of 1999Hu20 have very small uncertainties and have very large variations, up to 1.5%, with chemical form which need to be confirmed. If this large shift is correct, it would invalidate the uncertainty of our adopted value.

Prior to (2004Ti06) only one broad level had been confirmed for {+9}Be in the energy range between 6 and 7 MeV. New measurements, have confirmed the existence of a second level. As a result, the broad J|p=7/2- level that had previously been placed at 6.76 MeV has been relocated at 6.42 MeV. The newly identified level, a J|p=9/2+, has been placed at 6.76 MeV. Both levels are broad, greater than |G=1.2 MeV, and the evaluator has made a best estimate for determining the xref assignments. The xref assignments are ambiguous because in many cases authors simply refer to the (at that time only) known broad state near 6.8 MeV.

J$from 2014Lu04. In ENSDF J|p=9/2+ from {+9}Be(p,p') (1991Di03). The article aims to make comment on the J|p value of the E{-x}=11282 keV state. Part of the motivation is a claim that the E{-x}=11282 keV state is part of a rotational band with members E{-x}=0, 2429, 6760 and 11282 keV having J|p=3/2-, 5/2-, 7/2- and 9/2-, respectively. The issue is not simple; at the time of the 1988Aj01 review there was only one known broad level in the E{-x} |? 6.5 MeV range. However, two broad levels were found at E{-x}=6380 and 6760 keV with J|p=7/2- and 9/2+, respectively (1991Di03). In the present article, the E{-x}=6760 state is identified with J|p=7/2-; it is unclear if J|p=9/2+ was considered or if perhaps the E{-x}=6380 keV state was observed.

J$from 2014Lu04. In ENSDF J|p=(7/2-) from {+10}Be(e,e'p') (1993De02). The article makes detailed discussion on the J|p character of the E{-x}=11282 keV state. It is suggested that 1988Aj01 assigned the value J|p=9/2- to this state; no value was assigned in the main table of adopted values. The most recent review 2004Ti06 assigned J|p=(7/2-). The present result finds a good fit to the angular distribution using J|p=9/2- and by adjusting both the |b{-2} and |b{-4} parameters in the OM analysis. However, no comparative fit with previously reported J|p values is shown. In the present work, emphasis on the J|p=9/2- value appears motivated by the expectation of a J|p=9/2- state in this region as the member of a rotational band built on the J|p=3/2- ground state, and on the possibility that the states strongly populated in this experiment are all band members.

$A kinematic reconstruction of |a+3p events indicates a state at mass excess=27677 keV {I25}, which is |? 250 keV lower than the accepted value for {+7}B{-g.s.} (27.94 MeV {I10}). A width of |G=800 keV {I20} was deduced, which compares with 1.4 MeV {I2} from 1967Mc14. 
$The decay path was evaluated to determine the fraction of {+7}B{-g.s.} --> p+{+6}Be{-g.s.} decay events. Initial analysis indicated a (54 |+ {I6})% probability for p+{+6}Be{-g.s.} events in the data, though after correction for a broad background component a final ratio of {+7}Be{-g.s.} --> (81 |+ {I10})% p+{+6}Be{-g.s.} is deduced. This appears consistent with a shell model spectroscopic factor prediction S=0.688. 
$Discussion on the p+{+6}Be*(1.67 MeV; J|p=2+) decay branch is given. The p+{+6}Be(2+) configuration is expected to be 3 times larger than the p+{+6}Be{-g.s.}(0+) configuration in {+7}B{-g.s.}; however the p+{+6}Be(2+) channel is suppressed due to a smaller barrier penetration factor.

J,ISPIN$from Adopted Levels of {+8}|b in ENSDF database. 
The kinematic reconstruction of 2p+{+6}Li events implies either a state at E{-x}=7.06 MeV {I2} or 10.62 MeV {I2} (involving 2p+{+6}Li*(3562 keV)). The former is not expected while the later corresponds to the known IAS of {+8}C{-g.s.} and {+8}Be*(27.5).

E from (1966Br18) Q=9232.9 keV {I34}, however the presently calculated Q(|b{+-})value=9229.55 keV {I16} (2003Au03). Excited states up to E{-x}=6793.8 keV are from (1966Br18); it is presumed that the systematic error affecting the ground state energy measurement equally affected those excitation energies. The present ground state Q(|b{+-})value is used with the measured resonance energies to determine E{-x} for the higher-lying states. 
E significant discussion is given in (1966Br18) about the Q-value for the {+10}B(d,p) reaction and variations in earlier measurements. Of specific concern was placement of a |g-ray observed by (1964Al22) in {+11}Be decay. The |g-ray energy (6792 keV {I6}) placed the parent level between two known {+11}B levels and caused a correction of past measurements, due to an error in calibration source energy, and refinement in subsequent measurements.

As in (2004Ti02) we take the {+9}C branch feeding the {+9}B g.s. to be 54.1 from (2001Be51), where extra care was taken to avoid low-energy threshold concerns; the branches feeding other levels were taken from (2000Ge09) and renormalized to give a 100% feeding (|*46.9/54.1|?0.86). (2000Ge09) also found a large {Ibackground} branch (approx 4%), which was attributed to tails from higher states; this intensity is included but not attributed to any states.

T$ from 2009Ba06. The authors point out that weighted average of three literature values (2008Ia01,1990Ba02 and 1974Az01) and their measured value gives 19.305 s {I4} with |h{+2}=7.8 for three degrees of freedom; which represents an unsatisfactory situation from statistical viewpoint. Thus they suggest that it is premature to adopt a value of "FT" for superallowed beta transition and further progress in the measurement of this half-life should perhaps be awaited. 
$Compilers' note: literature values in sec are: 19.310 {I4} (2008Ia01), 19.300 {I41} and 19.294 {I16} (1990Ba02), 19.282 {I20} (1974Az01), 19.151 {I26} (1974Ro21), 19.270 {I80} (1963Ba52), 19.480 {I50} (1962Ea02). Combining these values with 19.282 {I11} from 2009Ba06 gives a weighted average of 19.303 {I10} with reduced |h{+2}=7.9. Using 19.282 {I11} (2009Ba06), 19.310 {I4} (2008Ia01), 19.294 {I16} (1990Ba02) and 19.282 {I20} (1974Az01) gives weighted average of 19.305 {I6} (external uncertainty) with reduced |h{+2}=2.6.

E Discussion of the {+10}Be level structure implies that only two levels are expected near E{-x}=6.55 MeV. Peaks at three different energies are observed in three of the observed {+10}C* decay channels. The evaluator assumes that, while three peaks are reported near E{-x}=6.55 MeV, there are only two levels. 
The evaluator assumes that the level at 6560 keV observed in |a+{+6}Be decay, which is listed as a possible doublet, actually represents the two states. 
The authors provided branching ratios for the 2p+{+8}Be and p+{+9}B decay channels, assuming that they represent the same level decaying in different paths, but it is unclear to the evaluator how any |a+{+6}Be branching ratio was considered, and it is unclear how contributions from either of the two levels near 6.55 MeV were deconvoluted.

J$From the measured relative energy between proton and the {+9}B core, it is apparent that the correlation is dominated by 1{Is}{-1/2}{+2} proton emission, which fixes the spin of the {+10}C* parent state as 0{++}. This is supported by the expected, sizable Thomas-Ehrman shift (0.892 MeV {I15} obtained in this study) observed between the energy of this level and its analog in {+10}Be.

T$From R-matrix intrinsic lineshape. 
J$From a comparison of the correlations between the two decay protons emitted by this state with those observed from the known {+2}He emitters such as {+6}Be*(2{++}{-1}), {+12}O*(2{++}{-1}, 2{++}{-2}), and {+16}Ne*(2{++}{-1}). These correlations all show enhancement of the {+2}He-like decay, which is considered as a fingerprint for the 2{++}|)0{++} decays, at least in this mass region. Thus, this state was assigned J{+|p}=2{++}. 
$This state is considered to be the second member of the 0{++}{-2} rotational band, whose bandhead is the {+10}C*(5.282 MeV, 0{++}) state. 
$This state is expected to have an |a-cluster structure. This assumption is supported by the reduced width of |g{-|a}{+2}=0.16 MeV {I7} deduced by (2022Ch02) for the |a-decay based on the total decay width and the branching ratio from this study. The authors also determined the dimensionless reduced decay widths of |g{-p}{+2}/|g{-pW}{+2}=0.03 {I1}, |g{-2p}{+2}/|g{-2pW}{+2}=0.09 {I4}, and |g{-|a}{+2}/|g{-|aW}{+2}=0.19 {I9}, where index W indicates the Wigner limit. These results show that the |a-decay is the strongest branch consistent with an |a-cluster structure. 
$Decay to p+{+9}B{-g.s.} with Branching=66% {I2}, 2p+{+8}Be{-g.s.} with Branching=18% {I1}, and |a+{+6}Be{-g.s.} with Branching=16% {I1}. The 2p decay branch is of {+2}He-like nature due to the strong enhancement of the small relative energy between the 2 decay protons.

$This state is tentatively considered to be the J{+|p}=4{++} member of the 0{++}{-2} rotational band, whose bandhead is the {+10}C*(5.282 MeV, 0{++}) state.

In the present evaluation, the higher precision E{-x}=9.93 MeV {I3} is accepted for a tentative state.

level_comment:
E,WIDTH$From (1966Sc23). 
$The R-matrix analysis of (2010Hy01) indicates the origin of the 10.3 MeV group is related to interference between the J{+|p}=0+ state at E{-x}=7.65 MeV and higher-lying strength near 11 MeV that, "gives the very broad component from 8.5 to 11 MeV, which has been mistaken for a 10.3 MeV resonance with a 3 MeV width". We continue to list this state because of the value of the historic record of reports and studies of the E{-x}=10.3 MeV group, and because of still unresolved questions on the J{+|p}=0+ (and 2+) strength in the E{-x}=9-13 MeV region. However, future studies may provide different and more complete interpretation of this region.
