Abstract

Experimental nuclear structure and decay data are evaluated for 9 known nuclides of mass number A=32 (F, Ne, Na, Mg, Al, Si, P, S, Cl, Ar). Detailed evaluated information is presented for each reaction and decay and recommended values combining all available data are provided for all spectroscopic properties of each level, γ transition, and decay radiation. Effort has been made to search for ³²F (2019Ah07) with no success, suggesting unbound towards neutron emission. Information for excited states in ³²Ne, ³²Na and ³²Ar are very limited, and spin-parity of ³²Na remains undetermined experimentally; only a few excited states have been identified in ³²Al, and the decay schemes of ³²Mg β⁻ decay to ³²Al and ³²Al to ³²Si are still incomplete; ³²Mg, ³²P and ³²S have been studied via various reactions and decays, with ³²S one of the most extensively studied nuclei in the sd-shell. This work supersedes earlier full evaluations of A=32 by 2011Ou01, 1998En04, 1990En08 and 1978En02.

A=32等压线的核结构和衰变数据

对质量数为A=32的9种已知核素（F、Ne、Na、Mg、Al、Si、P、S、Cl、Ar）的实验核结构和衰变数据进行了评价。详细的评估信息提供了每个反应和衰变，并结合所有可用数据提供了每个能级，γ跃迁和衰变辐射的所有光谱特性的推荐值。人们已经努力寻找32F (2019Ah07)，但没有成功，这表明它不受中子发射的束缚。32Ne、32Na和32Ar的激发态信息非常有限，32Na的自旋宇称仍未在实验中确定；在32Al中只发现了少数激发态，32Mg β−衰变到32Al和32Al到32Si的衰变方案仍然不完整；32Mg， 32P和32S已经通过各种反应和衰变进行了研究，其中32S是sd壳层中研究最广泛的原子核之一。这项工作取代了2011年01月、1998年04月、1990年08月和1978年02月对A=32的完整评估。
