Gamow-Teller strength distributions for double-beta-decaying nuclei within continuum-QRPA

Abstract

A version of the pn-continuum-QRPA is outlined and applied to describe the Gamow-Teller strength distributions for $\beta \beta$-decaying open-shell nuclei. The calculation results obtained for the pairs of nuclei ${}^{116}$Cd-Sn and ${}^{130}$Te-Xe are compared with available experimental data.
