Özet: In this study, the first forbidden beta transitions of states for ∆J=0 have been investigated in spherical odd mass nuclei. The pn-QRPA model is used with a schematic separable interaction to calculate first forbidden transitions by considering the Woods–Saxon potential basis in the Chepurnov parameterization. The transition probabilities in this model have been calculated within the ξ-approximation. ξ is a dimensionless parameter representing the magnitude of the Coulomb energy and is approximated by 1.2ZA−1/3 [1]. Logft values calculated of first forbidden transitions are found to be in better agreement with measured data.
