Abstract
In the present work, the matrix elements, isospin impurities and log ft values of the isospin forbidden 0+ → 0+ beta decays have been investigated. The calculated results have been compared with available experimental and another theoretical data. The isotopic invariance of the Hamiltonian has been restored by Pyatov method. Within the quasi-particle random phase approximation (QRPA), the computations have been performed both in presence and absence of the pairing interactions.
