Evaluated spectroscopic data and level schemes from radioactive decay and nuclear reaction studies are presented for 23N, 23O, 23F, 23Ne, 23Na, 23Mg, 23Al, and 23Si. This evaluation for A=23 supersedes the earlier one by R. B. Firestone (2007Fi02).

Highlights of this evaluation are the following:

The recommended absolute γ-ray emission probability (%Pγ) in the 23Ne β-decay was reported with 3.0% systematic uncertainty in 1986BrZQ. In 2007Fi02, the Pγ for the most intense γ ray was recommended with 4% uncertainty. These uncertainties are comparable with the total excited state β feeding uncertainty of 33 l, resulting from 100–67 l (g.s. β feeding) in 23Na (1963Ca06). In this evaluation, notes are added for relative and absolute γ-ray emission probabilities.

From new measurements 2020Kw01 constrain the spin of the 7788 keV level, the dominant resonance state for the 22Na(p,γ)22Mg reaction rate at stellar temperature, in 23Mg to (3/2+,5/2+). Earlier assignment was 7/2+.

The 23Al ε decay scheme appears to be incomplete. Some of the latest reported data on the 23Al ε decay study in the literature need verification.

A = 23的核数据表

提出了由放射性衰变和核反应研究得出的评估光谱数据和能级方案,涉及的是23 N,23 O,23 F,23 Ne,23 Na,23 Mg,23 Al和23 Si。对于A = 23的此评估取代了RB Firestone(2007Fi02)的较早评估。

该评估的重点如下:

推荐的绝对γ射线发射概率(%P γ中)23β衰变报道与1986BrZQ 3.0%,系统性不确定性。在2007Fi02,在P γ为最强烈的γ建议用4%的不确定性射线。这些不确定性都与总激发态可比β 33升的馈送的不确定性,从100-67升(GS所得β在喂养)23的Na(1963Ca06)。在此评估中,添加了有关相对和绝对γ射线发射概率的注释。

从新的测量值2020Kw01可以限制7788 keV水平的自旋,这是恒星温度下22 Na(p,γ22 Mg反应速率的主要共振态,在23 Mg至(3/2 +,5/2 +)之间。较早的任务是7/2 +

23的Al ε衰变方案似乎是不完整的。一些在最新的报告数据的23ε文献需要验证衰变研究。
