超核的粒子-空穴模型方法

A particle-hole model approach for hypernuclei

M. Martini, V. De Donno, C. Maieron, G. Co'

摘要:

本文发展了一个描述单λ超核激发谱的粒子-空穴模型,并通过与平均场计算的比较,探讨了集体效应的可能存在。给出了~(12)C、~(16)O、~(40)Ca、~(90)Zr和~(208)Pb单λ超核的光谱结果。与现有的实验数据进行比较是令人满意的。我们发现集体现象在超核中的重要性远低于在普通核中的重要性。

英文摘要:

A particle-hole model is developed to describe the excitation spectrum of single lambda hypernuclei and the possible presence of collective effects is explored by making a comparison with the mean-field calculations. Results for the spectra of 12C, 16O, 40Ca, 90Zr and 208Pb single lambda hypernuclei are shown. The comparison with the available experimental data is satisfactory. We find that collective phenomena are much less important in hypernuclei than in ordinary nuclei.
