In this case |?4.7|*10{+4} 18NE4c {+18}Ne ions/sec were implanted at 30 keV in an aluminized Mylar tape. 18NE5c After implantation, the beam was diverted and the tape was moved to 18NE6c a counting area at the center of a 4|p gas proportional counter 18NE7c that operated at 2750 V. Ions were implanted for a period of 0.5 sec 18NE8c prior to a few second transition to the counting position. The |b-rays 18NE9c from decay then were counted for 40 sec (|?24 half-lives). 18NE c In the second experimental conditions, the cold-transfer line was 18NE2c not utilized; the result was a higher intensity |?4.8|*10{+5} {+18}Ne 18NE3c ions/sec beam with a 1|*10{+6} {+18}F ions/sec contaminant (T{-1/2} 18NE4c |?6582 sec). In this case, the beam was implanted in the aluminized 18NE5c Mylar tape with 20 keV, and was counted with a different 4|p gas 18NE6c proportional counter that operated at 2450 V. 18NE c The |b-events were collected using two independent multichannel scaler 18NE2c modules that operated with fixed deadtimes of 3 and 4 |ms. A 18NE3c significant discussion on sources of systematic uncertainties is given 18NE4c in the text. The present results are dominated by statistical 18NE5c uncertainties. 18NE c The results of T{-1/2}=1.66424 s {I+72-64} and 1.66368 s {I+84-50} are 18NE2c independently obtained, resulting in the weighted average value of 18NE3c T=1.66400 s {I+57-48}. 18NE L 0 0+ 1.66400 S +57-48 18NE cL T$this half-life can be compared with the next most precise reported 18NE2cL values of T{-1/2}=1.6648 s {I11} (2013Gr03: Phys.

Kelley and C.G. Sheu (TUNL), Sept 22, 2015. 18NE c Edited by B. Singh (McMaster), Sept 22, 2015 18NE c The authors studied the astrophysically relevant {+14}O(|a,p) reaction 18NE2c at E{-cm}=2.1-5.3 MeV, in inverse kinematics, and identified resonant 18NE3c states. 18NE c A beam of 33.8 MeV {+14}O ions, produced via {+1}H({+14}N,{+14}O) 18NE2c reactions at the RIKEN Nishina Center, impinged on a 150 mm long 18NE3c {+4}He gas cell that was filled to 440 torr. As the beam 18NE4c slowed, {+4}He({+14}O,p) reactions occurred producing energetic proton 18NE5c ejectiles that were detected in a set of position sensitive |DE-|DE-E 18NE6c detectors. Three telescopes covered the angles from |q{-lab}=-12|'-78|' 18NE7c for reactions at the middle of the gas target. It is unclear if the 18NE8c precise proton ejectile angle was measured using the two successive 18NE9c position sensitive |DE-|DE detectors in the telescopes. A PPAC at the 18NEac entrance of the gas target provided a time signal that was compared 18NEbc with the time from a Si |DE/E detector. 18NE c By analyzing the reaction kinematics and the relative time-of-flight 18NE2c between the PPAC and Si telescope, it was generally possible to 18NE3c differentiate the p{-0,1,2,3} groups; further analysis took into 18NE4c account events from 2p emission events. The resulting excitation 18NE5c functions were analyzed using the SAMMY R-matrix analysis code to 18NE6c identify four {+18}Ne resonances that participated in the reaction. 18NE7c Astrophysical implications are discussed. 18NE CL T$LABEL=WIDTHA+WIDTHP 18NE L 7350 30 (1-) 390 KEV 40 18NE2 L WIDTHA=3.1 KEV 2 $ WIDTHP=387 KEV 40 18NE cL $Resonance strength |w|g=9.32 keV 18NE L 7580 20 (0+) 104 KEV 26 18NE2 L WIDTHA=1.5 KEV 5 $ WIDTHP=102 KEV 26 18NE cL $Resonance strength |w|g=1.52 keV 18NE L 7720 20 (2+,3-) 281 KEV 61 18NE2 L WIDTHA=1.9 KEV 3 $ WIDTHP=279 KEV 61 18NE cL $Resonance strength |w|g=5.38 keV 18NE L 8.10E3 10 (0+) 338 KEV 38 18NE2 L WIDTHA=40.4 KEV 49 $ WIDTHP=298 KEV 38 18NE cL $Resonance strength |w|g=35.0 keV 18NE L 8.50E3 10 (1-,2+) 631 KEV 64 18NE2 L WIDTHA=85 KEV 21 $ WIDTHP=546 KEV 60 18NE L 9.14E3 10 3- 495 KEV 59 18NE2 L WIDTHA=27.0 KEV 60 $ WIDTHP=468 KEV 59 18NE L 9600 90 (1-,0+) 0.63 MEV 10 18NE2 L WIDTHA=0.62 MEV 10 $ WIDTHP=7.8 KEV 66 18NE L 10070 80 (2+,1-) 92 KEV 18 18NE2 L WIDTHA=1.5 KEV 8 $ WIDTHP=90 KEV 18 18NE 2H(17F,18NE):XUNDL-14 2017KU27 201805 18NE c Compiled (unevaluated) dataset from 2017Ku27 18NE c Phys. Rev. C 96 {I045812} (2017) 18NE c Compiled by J. Kelley and C.G. Sheu (TUNL), April 19, 2018. 18NE c The authors measured the {+17}F(d,n)reaction in inverse kinematics 18NE2c to identify resonances that are important for the 18NE3c {+17}F(p,|g){+18}Ne reaction, which plays a role in the 18NE4c "hot CNO" cycle of stellar nucleosynthesis. 18NE c A beam of E({+17}F)=95.5 MeV ions, produced via 18NE2c {+2}H({+16}O,{+17}F) reactions at the Florida State/RESOLUT 18NE3c facility, impinged on a 520 |mg/cm{+2} Cd{-2} target that was 18NE4c surrounded by a variety of detector arrays. A cylindrical 18NE5c nine-fold segmented position sensitive gas ionization chamber 18NE6c was located 30 cm downstream of the target and was used to identify 18NE7c {+17}F and {+18}Ne ions after the target and to determine their 18NE8c momenta. An annular array of segmented |DE-E Si strip detectors 18NE9c was used to identify protons emitted from {+18}Ne*. The {+18}Ne 18NEac excitation energies were deduced from a kinematic reconstruction 18NEbc of the p+{+17}F energies; prominent levels at E{-x}=4523 and 5090 keV 18NEcc were analyzed to obtain spectroscopic factors and proton widths. 18NEdc An analysis of the measured spectra for the E{-x}=4523 state 18NEec confirm {Il}=0, as had been previously reported. 18NE c The reaction dynamics were further constrained with analysis of 18NE2c the resoneut neutron detector array, which is sensitive to 18NE3c low-energy neutrons. The neutron array was positioned 18NE4c 23.1 cm upstream of the target, and covered |q{-c.m.}=3|' to 10|' 18NE5c reaction angles. In addition, the APEX barrel array of 18NE6c 20 NaI(Tl) detectors surrounded the target and was used to 18NE7c detect |g rays. The neutron Time-of-Flight (ToF) was analyzed for 18NE8c p+{+17}F events, which was dominated by the E{-x}=4523 state, and 18NE9c for |g+{+18}Ne states, which found participation of 18NEac {+18}Ne*(1887,3376,3616). For these states, which are 18NEbc subthreshold for the astrophysically important {+17}F(p,|g) reaction, 18NEcc the data were analyzed to obtain spectroscopic factors and 18NEdc Asymtotic Normalization Coefficients (ANC). 18NE c Finally, using their results, the authors evaluated the 18NE2c astrophysical S-factor. 18NE cL E,J$From Adopted Levels of {+18}Ne in ENSDF database and 18NE2cL (1999Ba49,2010Ji02). 18NE L 1887 2+ 18NE cL $C{+2}S(2s{-1/2})=0.22 {I11}(stat) {I3}(syst), 18NE2cL C{+2}S(1d{-5/2})=0.88 {I42}(stat) {I11}(syst), ANC(2s{-1/2})=16.0 18NE3cL fm{+-1} {I77}(stat) {I21}(syst), 18NE4cL ANC(1d{-5/2})=2.6 fm{+-1} {I12}(stat) {I3}(syst).

Kelley (TUNL), August 24, 2024. 18NE c The authors studied the {+2}H({+18}Ne,t) and {+2}H({+18}Ne,{+3}He) 18NE2c single nucleon pickup reactions and reanalyzed the existing data of 18NE3c the {+18}O(d,t) and {+18}O(d,{+3}He) mirror reactions that were 18NE4c acquired at similar incident energies by (1971Ha48, 1977Ma10) to 18NE5c investigate the effects of nucleon binding energy and continuum 18NE6c coupling on the mirror symmetry of spectroscopic factors of mirror 18NE7c levels. 18NE c The experiment was performed at the SPIRAL facility at GANIL, where a 18NE2c 16.5 MeV/nucleon {+18}Ne beam impinged on a Cd{-2} target. The 18NE3c {+2}H({+18}Ne,t); {+2}H({+18}Ne,{+3}He); and {+2}H({+18}Ne,d') 18NE4c reactions were studied. The heavy reaction products and residuals from 18NE5c their in-flight decay were momentum analyzed using the VAMOS 18NE6c spectrometer. The energy loss, emission angle, and ToF of these 18NE7c particles were measured using the focal plane detection system. Similar 18NE8c properties of the light reaction products and (in)elastically scattered 18NE9c deuterons were measured using the MUST2 array, which surrounded the 18NEac target. This array consisted of 4 position sensitive |DE-E telescopes 18NEbc placed at forward angles to detect reaction products, and 2 similar 18NEcc telescopes placed at |q{-lab}=90|' to measure the scattered deuterons. 18NEdc An average energy resolution of 40 keV (FWHM) and angular resolution 18NEec of 0.4|' (FWHM) were achieved. Angular distributions and differential 18NEfc cross sections of the above mentioned reactions were measured 18NEgc exclusively. 18NE c The authors deduced the excitation energy spectrum of {+18}Ne from the 18NE2c {+2}H({+18}Ne,d') scattering. They used the continuum discretized 18NE3c coupled-channels analysis via the FRESCO code to fit the angular 18NE4c distributions of the {+18}Ne{-g.s.} and {+18}Ne*(2{++}{-1}) states. 18NE L 0 0+ 18NE cL J$From the {+18}Ne Adopted Levels.

Rev. C 112, 015810 (2025). 18NE c Compiled by K. Setoodehnia and J. Kelley (TUNL), August 8, 2025. 18NE c The authors performed a resonant elastic scattering measurement to 18NE2c deduce properties of the {+18}Ne states just above the proton 18NE3c threshold. These states are significant in determination of the 18NE4c {+14}O(|a,p) reaction rate at the temperatures relevant to type I 18NE5c X-ray bursts. 18NE c The experiment was carried out at the John D. Fox Superconducting 18NE2c Accelerator Laboratory at Florida State University. A 54.7-MeV {+17}F 18NE3c beam was produced using the {+16}O(d,n) reaction and a 79-MeV {+16}O 18NE4c primary beam. The RESOLUT radioactive ion beam facility was used to 18NE5c identify and separate the {+17}F beam particles in flight. This beam 18NE6c impinged on a 2.05-mg/cm{+2} polypropylene target. The scattered 18NE7c protons from the {+1}H({+17}F,p) resonant elastic scattering were 18NE8c measured by a position sensitive |DE-E Si telescope covering 18NE9c |q{-lab}=8|'-24|' with a resolution of 42 keV at (FWHM) in the 18NEac center-of-mass frame. The energy loss and residual energies of the 18NEbc recoiling {+17}F ions were measured in coincidence with those protons 18NEcc using a gas-filled ionization chamber downstream the target. 18NE c The {+18}Ne excitation function covering E{-x}({+18}Ne)=5.9-6.9 MeV was 18NE2c deduced from kinematics reconstruction. Two {Is}-wave proton resonances 18NE3c were observed (one of which is an unresolved doublet), whose properties 18NE4c were determined using a multichannel R-matrix analysis via the AZURE2 18NE5c software with a channel radius of 4.864 fm. Depending on the choice of 18NE6c the J{+|p} values used in the R-matrix analysis, the authors deduced 18NE7c two sets of parameters for the measured resonances. The resulting 18NE8c variation in the deduced nuclear structure properties of the observed 18NE9c states introduces a factor of 6 change in the {+14}O(|a,p) rate over 18NEac the temperature range of interest for the Type I X-ray bursts. However, 18NEbc the present data alone cannot conclusively constrain the J{+|p} values 18NEcc for the two measured resonances, or improve the fit to the inelastic 18NEdc scattering data of (2012Ba28). 18NE c It should be noted that the present study refitted (using R-matrix) 18NE2c the data from (2014Hu16) in the E{-x}({+18}Ne)=5.8-7.4 MeV 18NE3c region. This fit did not include the present data. Inclusion of the 18NE4c presently deduced resonant parameters regardless of the J{+|p} choice 18NE5c does not affect the fit to the data of (2014Hu16). The authors claim 18NE6c to have achieved a better fit than the original study of (2014Hu16) by 18NE7c using a channel spin=2 instead of 3 (original). The resultant 18NE8c excitation energy for a known 4{++} state around 7 MeV is 7.12 MeV 18NE9c {I2}, which differs by >46 keV from the original analysis. 18NEac The present study recommends using E{-x}=7065 keV and |G{-p}=151 keV 18NEbc for this J{+|p}=4{++} state. Moreover, the present reanalysis does not 18NEcc find evidence for the tentative J=0 state at 6.85 MeV reported by 18NEdc (2014Hu16) and reports that the higher energy 7.37-MeV state is better 18NEec fitted with a J{+|p}=0{++} state rather than the original 2{++} 18NEfc assignment. 18NE CL T$LABEL=|G 18NE cL E,J,T,WIDTHP0,WIDTHP1$From a multichannel R-matrix analysis via the 18NE2cL AZURE2 software with a channel radius of 4.864 fm. 18NE cL WIDTHP1$These values were kept fixed in the R-matrix and differ 18NE2cL depending on the choice of J{+|p} used. 18NE cL E(A)$Member of an unresolved doublet. 18NE cL E(B)$Suggested in the present work from a reanalysis of the data of 18NE2cL (2014Hu16). 18NE cL E(C),T(C)$An equally well describing fit to the present data was 18NE2cL achieved using (1) E{-x}=6145 keV {I6} with J{+|p}=3{+-}, |G=10 keV 18NE3cL {I+3-2}, and |G{-p{-1}}=5 keV, which was kept fixed; (2) E{-x}=6342 18NE4cL keV {I+10-15} with J{+|p}=1{+-} and |G{-p{-0}}=15 keV {I+11-15}; and 18NE5cL (3) E{-x}=6406 keV {I+13-28} with |G{-p{-0}}=16 keV {I+12-13}. 18NE L 6134 8 1- 51 KEV +18-12 18NE2 L WIDTHP1=15 KEV 18NE3 L FLAG=C 18NE L 6.30E3 5 3- 18NE2 L WIDTHP0 LT 36 KEV 18NE3 L FLAG=AC 18NE L 6.35E3 4 2- 18NE2 L WIDTHP0=90 KEV +55-36 18NE3 L FLAG=AC 18NE cL E$From 6.35 MeV {I+3-2}. 18NE cL E,T,WIDTHP0$Deduced by assigning J{+|p}=1{+-} to the state at 6.1 MeV 18NE2cL and J{+|p}=3{+-} to the lower-energy member of the doublet at 6.3 MeV. 18NE cL WIDTHP0$The {I+55} keV upper uncertainty is deduced without inclusion 18NE2cL of the J{+|p}=3{+-} state at 6.3 MeV. 18NE L 7065 18NE2 L WIDTHP0=151 KEV 18NE3 L FLAG=B 18NE cL WIDTHP0$Suggested in the present work from a reanalysis of the data of 18NE2cL (2014Hu16). 18NE 1H(17F,P'):RES:XUNDL-19 2025CO18 202512 18NE c Compiled (unevaluated) dataset from 2025Co18. 18NE c Phys.

This resonance dominates the 18NE3c {+14}O(|a,p) reaction rate at temperatures relevant to explosive 18NE4c burning in type I X-ray bursts. 18NE c The experiment was performed at the University of Notre Dame Nuclear 18NE2c Science Laboratory, where {+17}F beams with E=38-42 MeV (in |?500 keV 18NE3c increments) were produced from the {+2}H({+16}O,n) reaction using the 18NE4c TriSol facility and a deuterium gas target. The {+17}F beam with 18NE5c varying energies had a 800 keV energy spread and 0.8|' angular spread 18NE6c (at FWHM) and it impinged on a CH{-2} target. The scattered protons 18NE7c from {+1}H({+17}F,p),({+17}F,p') were measured using an array of two 18NE8c position sensitive |DE-E Si telescopes covering |q{-lab}=8.7|'-20.4|'. 18NE9c The recoiled {+17}F particles were measured in coincidence with the 18NEac protons using a P10-filled, position sensitive ionization chamber, 18NEbc which was placed downstream of the target. 18NE c The excitation energy spectrum of {+17}F was reconstructed from the 18NE2c protons corresponding to the decay of a resonance at 18NE3c E{-c.m.}({+17}F+p)=2170 keV {I8}.
