The investigation of the log (ft) values for the allowed Gamow-Teller transitions of some deformed nuclei

Abstract

The log(ft) values of allowed $\beta^\pm$ decay between odd-A nuclei for $125\leq A\leq 180$ mass region are investigated. Single particle energies and wave functions are calculated by making use of a deformed Woods-Saxon potential. The calculations are performed in the framework of proton-neutron quasi particle random phase approximation (QRPA) including the schematic residual spin-isospin interaction among the nucléons in the particle hole channel. The calculations indicated that the results obtained through using the $\chi_{GT}=5.2/A^{0.7}$ are more in agreement with experimental observations.
