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 ?-approximation. ? 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.eninfo:eu-repo/semantics/openAccessArticle174182
