Running sums for $2\nu \beta \beta$-decay matrix elements within the QRPA with account for deformation

Dongliang Fang, Amand Faessler, Vadim Rodin +2

The $2\nu \beta \beta$-decay running sums for ${}^{76}$Ge and ${}^{150}$Nd nuclei are calculated within a QRPA approach with account for deformation. A realistic nucleon-nucleon residual interacti…
