The present study investigates the log(ft) values of the allowed β± decay between odd-A deformed nuclei in the atomic mass regions of 125 ≤ A ≤ 131 and 159 ≤ A ≤ 181. Single particle energies and wave functions have been calculated with a deformed Woods-Saxon potential. Calculations have been performed within the framework of a proton-neutron quasi-particle random phase approximation (QRPA), including the schematic residual spinisospin interaction between nucleons in the particle-hole and particle-particle channels. It has been seen that the results obtained by using the values for the fixed particle-hole and particle-particle interaction strengths, ΧGTph = 5.2/A0.7 MeV and ΧGTpp = 0.58/A0.7 MeV, have good agreement with the experimental observations.
