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.
