Abstract
The present study investigates the log(ft) values of the allowed beta(+/-) decay between odd-A deformed nuclei in the atomic mass regions of 125 less than or equal to A less than or equal to 131 and 159 less than or equal to A less than or equal to 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 spin-isospin 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, chi(GT)(ph) = 5.2/A(0.7) MeV and chi(GT)(pp) = 0.58/A(0.7) MeV, have good agreement with the experimental observations.
