    • Abstract


      The $0^{+} \leftrightarrow 0^{−}$ first-forbidden 𝛽 decay transitions have been investigated for some spherical nuclei. The theoretical framework is based on a proton–neutron quasiparticle random phase approximation (pnQRPA). The Woods–Saxon potential basis has been used in our calculations. The transition probabilities have been calculated within the 𝜉 approximation. The relativistic 𝛽 moment matrix element has been calculated both directly without any assumption and assuming that it is proportional to the non-relativistic one.
