摘要
本文在α集团模型下,利用谐振子基展开和广义Talmi-Moshinsky变换,完成了对Λ超核_Λ~9Be、_(ΛΛ)~6He和_(ΛΛ)^(10)Be能谱的变分计算.借助统一的α-α、Λ-Λ势和修正的Λ-α势,使_Λ~9Bc、_(ΛΛ)~6He和_(ΛΛ)^(10)Be的能级得到自洽的描述.此外,对上述三个Λ超核的结构和粒子间的关联也作了研究和分析,得到一些有意义的结果.
Based on the α-cluster models, variational calculations for _∧~9Be, _(∧∧)~6He and _(∧∧)^(10)Bc have been completed with the aid of the harmonic oscillator expansions and the generalized Talmi-Moshinsky transformations. Under uniform α-α and ∧-∧ potentials, the unified descriptions for _∧~9Be, _(∧∧)~6He and _(∧∧)^(10)Be are achieved by introducing a modified ∧-α potential. We have also studied the structures and correlations between particles in the calculated states of these hypernuclei and obtained some interesting results.
