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.
