Reconstruction of the complete kinematics permitted an 8B 4c analysis of excitation energies, decay pathways and associated 8B 5c branching ratios for several nuclei. 8B c A beam of 150 MeV/nucleon {+16}O ions was fragmented in a thick {+9}Be 8B 2c target to produce a 70 MeV/nucleon {+9}C beam in the NSCL A1900 8B 3c fragment separator. The {+9}C beam impinged on a 1mm thick {+9}Be 8B 4c target and reaction products were detected in 14 position sensitive 8B 5c |DE-E elements of the HiRA array. The coincident reaction products 8B 6c were analyzed via kinematic energy reconstruction to evaluate 8B 7c excitation energies and decay paths. 8B c States in {+8}B are observed in the p+{+3}He+|a, 2p+{+6}Li and 2p+d+|a 8B 2c exit channels.

C 82, 041304), the authors measured 8B 2c the multiproton decay properties of {+8}B*(10610) by measuring the 8B 3c complete kinematics of all the decay products. In the present case, the 8B 4c observations were enhanced by the measurement of electromagnetic decay 8B 5c radiations. 8B c A beam of 68 MeV/nucleon {+9}C ions was produced by fragmenting a 8B 2c {+16}O beam on a thick beryllium target at the NSCL/A1900 separator 8B 3c facility. The beam then impinged on a 1 mm thick {+9}Be target; the 8B 4c charged particles from {+9}Be({+9}C,{+8}B --> 2p+{+6}Li) reactions were 8B 5c detected using the position sensitive HiRA detector array, while any 8B 6c associated |g-rays were detected using the CAESAR CsI array. Analysis 8B 7c of the kinematic excitation spectrum, along with the associate |g-ray 8B 8c coincidences permitted a detailed determination of the {+8}B*(10610) 8B 9c decay properties. 8B c The decay is found to proceed mainly to {+6}Li*(3560), which is the IAS 8B 2c of {+6}Be. Hence, similar to the {+8}C 2-proton decay to {+6}Be, 8B 3c {+8}B*(10610: IAS of {+8}C) 2-proton decays to {+6}Li*(3560: IAS of 8B 4c {+6}Be).

The reactions 8B 6c produced short-lived levels that proton decayed before exiting the 8B 7c target. The decay of {+8}B*(770,2320) were studied in order to 8B 8c clarify their decay modes and possible involvement of 8B 9c {+7}Be*(429 keV). 8B c In the present case, a {+9}C beam was produced at the NSCL by 8B 2c fragmenting a {+16}O beam in the A1900 beam separator. The {+9}C beam 8B 3c impinged on a 1 mm thick {+9}Be target, which populated 8B 4c {+8}B states by proton-removal reactions. The unbound {+8}B states 8B 5c quickly decayed via proton emission. 8B c The complete kinematics of the charged-particle reaction products were 8B 2c measured using the HiRA array, which comprised a set of 14 8B 3c 64 mm |* 64 mm 8B 4c position sensitive |DE-E telescopes that covered the forward direction 8B 5c of the outgoing beam (|q{-lab}|?2|' to 13.9|'). The telescopes were 8B 6c arranged in vertical towers with a 2-3-4-3-2 configuration where the 8B 7c central tower had a gap between the upper and lower two telescopes to 8B 8c permit the beam a downstream exit at |q=0|'. 8B c In addition, 158 CsI(Na) crystals from the CAESAR array covered polar 8B 2c angles between |q{-lab}=57.5|' and 142.4|' and measured the coincident 8B 3c |g-ray deexcitations. 8B c The p+{+7}Be invariant-mass spectrum is dominated by two 8B 2c peaks corresponding to {+8}B*(770,2320). In addition, a small peak 8B 3c near 340 keV corresponds to {+8}B*(770) decay via 8B 4c p+{+7}Be*(429 keV) since the missing |g-ray energy is not included. 8B 5c Analysis of the HiRA and CAESAR data permitted a determination of 8B 6c the {+8}B relative decay intensities via p+{+7}Be{-g.s.} and 8B 7c p+{+7}Be*(429 keV); branching ratios of (98.9 |+1.8)% and 8B 8c (1.1 |+0.3)% were deduced, respectively. 8B CL T$LABEL=WIDTH 8B cL E,J,T$From 2004Ti06. 8B L 769.5 25 1+ 35.6 KEV 6 8B 2 L ISPIN=1 8B cL $Decays (98.9|+1.8)% via p+{+7}Be{-g.s.} and 8B 2cL (1.1|+0.3)% via p+{+7}Be*(429 keV). 8B L 2320 20 3+ 350 KEV 30 8B 2 L ISPIN=1 8B cL $Decays via p+{+7}Be{-g.s.}. 8B 1H(8B,P):XUNDL-8 2018KO13 201808 8B c Compiled (unevaluated) dataset from 2018Ko13 8B c Phys.

Sheu (TUNL), March 03, 2020. 8B c The authors studied elastic and inelastic {+7}Be+p scattering 8B 2c at low energies to determine the {Is}-wave scattering lengths, which 8B 3c are important to estimate the relevant astrophysical 8B 4c S{-17} capture rate. 8B c A {+7}Be sample, produced at the TUNL tandem accelerator, 8B 2c was transported to ORNL where it was chemically purified 8B 3c for use in the Holifield cesium sputter source. The resulting {+7}Be 8B 4c ions were accelerated to cover scattering energies from 8B 5c E{-c.m.}=0.474-2.740 MeV (E{-lab}=4-16 MeV). 8B 6c CH{-2} and CH{-2} targets deposited on gold backings were used at each 8B 7c energy. Scattered protons were collected using the 8B 8c SIDAR array operated in the flat configuration. In the flat 8B 9c configuration, the SIDAR's wedge shaped Si strip detectors 8B ac cover an annular area 8B bc around the beam axis; data were collected at two different distances 8B cc from the target providing data at |q{-lab}=14|'-31|' and at 8B dc |q{-lab}=26|'-50|' (covers |q{-cm}=70|'-150|'). At the lower beam 8B ec energies, the {+7}Be+p angular distributions are normalized to the 8B fc {+7}Be+{+12}C Rutherford cross section, while at higher energies the 8B gc data are normalized to the {+7}Be+Au cross sections. 8B c The present data are combined with low-energy data from (2003An06) and 8B 2c analyzed using the AZURE2 R-matrix code. The inelastic data was poorly 8B 3c fit using only the known {+8}B*(0, 0.77, 2.32, 3.52 MeV) states. 8B 4c The addition of levels at E{-x}=1.9 , 2.21 and 9.0 MeV with 8B 5c J{+|p}=0+, 2+ and 1-, respectively, significantly improves the 8B 6c fit. The authors also investigated evidence for a J{+|p}=1+ state near 8B 7c 3 MeV, as has been suggested by (1998Go16, 2013Mi05), and found 8B 8c no supporting evidence in the present data. 8B c Lastly, the {Is}-wave scattering lengths for channel spins 1 and 2, 8B 2c {Ia}{-01}=17.34{++1.11}{--1.33} fm and 8B 3c {Ia}{-02}=-3.18{++0.55}{--0.50} fm, are deduced, and implications 8B 4c for the astrophysical S{-17} capture rate are discussed. 8B cL DICT$({+7}Be,p)=({+7}Be,p) 8B CL T$LABEL=|G 8B L 0 2+ 8B L 0.77E3 1+ 8B L 1.9E3 1 0+ 0.55 MEV 13 8B cL $|G{-p0}=120 keV {I28} and |G{-p1}=0.43 MeV {I13} 8B L 2.21E3 4 2+ 254 KEV 9 8B cL $|G{-p0}=24 keV {I9} and |G{-p1}=230 keV {I1} 8B L 2.32E3 3+ 8B L 3.52E3 2- 8B L 9.0E3 1- 8B 12C(P,8B):XUNDL-10 2020VI03 202009 8B c Compiled (unevaluated) dataset from 2020Vi03 8B c Acta Phys.

Sheu (TUNL), August 27, 2020. 8B c The authors made three independent determinations of the {+8}B 8B 2c half-life, which is necessary to interpret results from their 8B 3c study of isospin mixing in the 8B 4c J{+|p}=2+ {+8}Be*(16626,16922) nuclear states. 8B c Details on beam production are found in (2019Ba23). 8B 2c The {+8}B ions were produced by spallation reactions induced by 8B 3c 1.4 GeV protons on a multi-walled carbon nanotube target 8B 4c at the CERN-ISOLDE facility. 8B 5c The target was maintained at controlled temperatures between 8B 6c 1500-1750 |'C, and a constant flow of a florinated gas, SF{-6}, 8B 7c was bled into the target assembly. A resulting {+8}BF{-2} molecular 8B 8c component was extracted from the spallation target. 8B 9c Typically, the PS-Booster operates with 36 proton beam pulses over 43 8B ac seconds (1.2 s periodicity); though in this case the beam from every 8B bc fifth pulse was used giving a 6 second period for 8B cc collecting activity and counting. 8B c The beam was implanted into a 31 |mg/cm{+2} thick carbon catcher 8B 2c foil that was perpendicular to the beam and 8B 3c at the center of an array of four position sensitive 8B 4c silicon |DE-E telescopes in the horizontal plane. 8B 5c The decay of {+8}B was recorded by detecting back-to-back |a particles 8B 6c following decay of the daughter {+8}Be. One pair of telescopes was at 8B 7c |q=+45|' and -135|' and was comprised of 60 |mm thick |DE detectors 8B 8c and 1500 |mm thick E detectors; the other pair was placed at 8B 9c |q=-45|' and +135|' and was comprised of 40 |mm thick |DE detectors 8B ac and 1000 |mm thick E detectors. 8B bc An additional 1000 |mm thick position sensitive E detector was 8B cc placed at |q=90|' in the vertical plane, below the other telescopes. 8B dc All the thresholds were set above 2.5 MeV so that the |a-particles 8B ec from {+8}Be decay originated from levels above {+8}B{+*}(3.0 MeV). 8B c Three independent results for the lifetime were obtained 8B 2c from the two pairs of detectors and the single out-of-plane E 8B 3c detector. Deadtime corrections and other systematic effects are 8B 4c briefly discussed. 8B 5c The values T{-1/2}(|a+|a in 60 |mm DSSD)=771.9 ms {I17}, 8B 6c T{-1/2}(|a+|a in 40 |mm DSSD)=773.9 ms {I18}, and 8B 7c T{-1/2}(|a in 1000 |mm DSSD)=770.9 ms {I27} were deduced. 8B 8c In the discussion, the authors averaged these values to obtain 8B 9c 772.2 ms {I10}, and they averaged with T{-1/2}=770 ms {I3} (1974Aj01) 8B ac to obtain T{-1/2}=771.17 ms {I94}. 8B c The compiler notes that uncertainties from statistical and 8B 2c systematic effects must be treated separately. In general it is 8B 3c assumed that systematic uncertainties dominate T{-1/2} measurements, 8B 4c and systematic uncertainties cannot be decreased with 8B 5c weighted averaging. 8B 6c Hence our practice in ENSDF is to limit the averaged uncertainty to the 8B 7c value of the most precise measurement. 8B L 0 2+ 0.7722 S 10 8B cL T$ Reported in the text from the average of three 8B 2cL independent measurements.
