A Microscopic Description of the Beta Decay of Dy168 using the Gamow-Teller Force

Raden Oktova

Abstract

A description of the beta decay of the nucleus Dy168 is presented using the Gamow-Teller force in the frame of the protonneutron Quasiparticle Random Phase Approximation (pn-QRPA). The single-particle ground states are obtained self-consistently using the Fayans energy density functional in an HFB scheme, and the quasiparticle states are built on the single-particle ground states using the BCS approximation. The calculation gives two Gamow-Teller transitions as expected, a half-life about one third of the experimental value, and a decay energy close to the experimental value.
