Analysis of the 2 nu beta beta decay and muon-capture reactions for the mass A=46 and A=48 nuclei using the nuclear shell model

摘要

We discuss the two-neutrino double-beta decays of Ca-46 and Ca-48 by using the nuclear shell model with well-tested two-body interactions. We also discuss the ordinary muon-capture (OMC) reaction on the final nuclei, Ti-46 and Ti-48, of these decays. The OMC leads to the virtual states of the intermediate nuclei, Sc-46 and Sc-48, in these double-beta decays. (C) 2004 MAIK "Nauka/Interperiodica".
