The energy levels of 23Na

New measurements of low-energy resonances in theNe22(p,γ)Na23reaction

“…As shown in Fig. 9, the strengths derived from the singles and coincidence are consistent with one another and agree well with previous results, once the latter are corrected as follows: The strength measured by Meyer et al [50] was initially obtained relative to the strength of the 640-keV resonance in the 22 Ne(p,γ) 23 Na reaction, reported in Ref. [51], but was subsequently renormalized by Endt [20] using the 1279-keV 22 Ne(p,γ) 23 Na resonance strength reported in Ref.…”

“…Adding this missing strength would imply ωγ(417 keV) = 0.088(7) eV. Nonetheless, there is excellent agreement between the present results, the revised strength from Meyer et al [50] and the published value from Depalo et al [31]. Consequently, we have taken a weighted average of the results of Refs.…”

“…Consequently, we have taken a weighted average of the results of Refs. [50], [31], and the unweighted average of our singles and coincidence results. This yields a recommended ωγ(417 keV) = 0.082(5) eV.…”

“…III A by considering all potential L = 1 & 2 transitions from the resonant state, as opposed to only those transitions that were previously reported in Ref. [50] and Ref. [31].…”

“…Branching ratios for decays from this resonance, calculated using both singles-and coincidence-detection modes are listed in Table I alongside the previous results of Refs. [31,50] for comparison. Recommended branching ratios calculated from the unweighted average of singles and coincidence values are shown in Table V alongside the recommended branching ratios for the other resonances measured for this work.…”
