Hindrance factors of unfavored α decay transitions to duplicated daughter states of the same spin and parity

We investigate the hindrance of the unfavored α-decay modes to the different daughter states, which have different spin than that of the parent nucleus but of the same parity. The duplicated daughter nucleus states of identical spin-parity (J π ) are ascendingly ordered according to the sequence of their excitation energy. We found that the hindrance of the unfavored decay modes increases with increasing the difference in spin (ΔJ) between the...
