Description

In this article, we analyze some nuclear-structure aspects of the 0ν double-beta decay nuclear matrix elements (NME). 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 NMEs 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 NMEs. (orig.)
