Abstract

Gamow-Teller
(GT) transitions for ⁷⁶Ge using QRPA methods in this article are
calculated, which play an essential role in the supernovae. Three different
QRPA models are used to the GT strength distributions. QRPA models namely
single quasi-particle (sqp), Pyatov Method (PM) and the Schematic Model (SM).
Gamow-Teller distribution, ΣB(GT)_-, the centroid of energy, the width of energy and ISR are calculated by using
these models. The effect
of particle-particle interaction on spherical nuclei and deformed nuclei on Gamow-Teller transitions is wanted to show.
Deformed Woods-Saxon potential
is used in calculations of Single-particle energies and wave functions. The results are also compared with previous
theoretical calculations and measured
strength distributions wherever available. It is expected that the current study of GT features would be helpful and may
guide to a better knowledge
of the presupernova progression of massive stars.

Keywords

Gamow Teller Distribution, Germanium Isotope, Centroid of Energy, Width of Energy, β-decay and Electron Capture.
