无中子双β衰变的原子核结构

Nuclear Structure Aspects of the Neutrinoless Double Beta Decay

E. Caurier, F. Nowacki, A. Poves

摘要:

本文在相互作用壳层模型的框架下,分析了无中微子双β衰变核矩阵元(NME)的某些原子核结构性质。利用改进的有效相互作用和价空间,给出了~(48)Ca,~(76)Ge,~(82)Se,~(124)Sn,~(128)Te,~(130)Te和~(136)Sn的衰变结果.我们考察了NME对有效相互作用和价空间的依赖性,并分析了短程关联和有限核子尺寸的影响。最后,我们研究了变形对NME值的影响。

英文摘要:

In this article, we analyze some nuclear structure aspects of the neutrinoless double beta decay nuclear matrix elements (NME), in the framework of the Interacting Shell Model. We give results for the decays of 48Ca, 76Ge, 82Se, 124Sn, 128Te, 130Te, and 136Xe, using improved effective interactions and valence spaces. We examine the dependence of the NME's on the effective interaction and the valence space, and analyze the effects of the short range correlations and the finite size of the nucleon. Finally we study the influence of the deformation on the values of the NME's.
