## Abstract

This paper presents a calculation of the beta^- decay of the neutron-rich nucleus Nd152 using the proton-neutron Quasi-particle Random Phase Approximation (pnQRPA) model. The

single-particle ground states are calculated self-consistently using the Fayans energy density

functional in a Hartree-Fock-Bogoliubov (HFB) scheme for deformed nuclei. The quasiparticle states which are needed for the pnQRPA calculation are calculated from the HFB

single-particle ground states using the Bardeen-Cooper-Schriefer (BCS) approximation. Only Gamow-Teller

beta^- excitations are considered, and two kinds of excitation force are used to excite the daughter nucleus to produce the

beta^- decay: (a) a pure Migdal force, and (b) a

Migdal force plus a correction term obtained self-consistently from the BCS quasi-particle

basis. The calculations with the pure Migdal force and the corrected Migdal force give halflives of 5.92 min and 6.91 min, respectively, which are about one half of the experimental

value of 11.6(7) min, and decay energies of 1.38 MeV and 1.33 MeV, respectively, both close

to the experimental decay energy of 1.12 MeV. The correction to the Migdal excitation force

turns out to improve the accuracy of the calculations.
