p壳层超核的壳模型计算

Shell-model calculations for p-shell hypernuclei

D. J. Millener

摘要:

本文简要回顾了用壳模型计算方法解释p壳层超核的γ射线数据,包括Lambda-和Sigma-超核子态的耦合。接下来,考虑了Lambda 8Li、Lambda 8Be和Lambda 9 Li,它们都表现出Lambda-Sigma耦合的特征,并且可能是观测到的但未分配的超核伽马射线的来源。然后,测量的Lambda 10 Be,这是像Lambda 9 Li,可以通过(K-,π 0 γ)反应进行研究的基态双峰间距的可行性进行了研究。在最近的(e,e 'K+)的研究中,这些超核的状态人口的结构信息也给出了。最后,壳模型计算的扩展到sd-壳超核被简要考虑。

英文摘要:

The interpretation of hypernuclear gamma-ray data for p-shell hypernuclei in terms of shell-model calculations that include the coupling of Lambda- and Sigma-hypernuclear states is briefly reviewed. Next, Lambda 8Li, Lambda 8Be, and Lambda 9Li are considered, both to exhibit features of Lambda-Sigma coupling and as possible source of observed, but unassigned, hypernuclear gamma rays. Then, the feasibility of measuring the ground-state doublet spacing of Lambda 10Be, which, like Lambda 9Li, could be studied via the (K-,pi0 gamma) reaction, is investigated. Structural information relevant to the population of states in these hypernuclei in recent (e,e'K+) studies is also given. Finally, the extension of the shell-model calculations to sd-shell hypernuclei is briefly considered.
