Ge同位素的壳模型描述

Shell model description of Ge isotopes

J. G. Hirsch, P. C. Srivastava

摘要:

本文用壳层模型研究了$38\leq N\leq 50$的低能谱,分析了激发能、四极矩、$B(E2)$值和占位数。理论计算结果与已有的实验数据进行了比较。壳模型计算采用了三种不同的有效相互作用和价空间,其中价空间$f_{5/2} \, p \,g_{9/2}$采用了两种有效的壳模型相互作用JUN 45和jj 44 b,没有截断。为了在价空间中包括质子子壳层$f_{7/2}$,我们采用了Sorlin { \it et al.}提出的$fpg$有效相互作用,其中$^{48}$ Ca作为核,并截断激发粒子的数量。

英文摘要:

A shell model study of the low energy region of the spectra in Ge isotopes for $38\leq N\leq 50$ is presented, analyzing the excitation energies, quadrupole moments, $B(E2)$ values and occupation numbers. The theoretical results have been compared with the available experimental data. The shell model calculations have been performed employing three different effective interactions and valence spaces.We have used two effective shell model interactions, JUN45 and jj44b, for the valence space $f_{5/2} \, p \,g_{9/2}$ without truncation. To include the proton subshell $f_{7/2}$ in valence space we have employed the $fpg$ effective interaction due to Sorlin {\it et al.}, with $^{48}$Ca as a core and a truncation in the number of excited particles.
