AbstractEffects of differences between neutron and proton distributions on a decay are investigated for odd-mass nuclei within the generalized density-dependent cluster model. The neutron skin thickness is employed to gauge the differences and it is considered in numerically computing the double-folding a-nucleus potentials. In terms of the characteristic of odd-mass a emitters, special attention is paid to the a decays from ground or isomeric states which end in the ground states of daughter nuclei and furthermore belong to favored a decays. The calculations with the neutron skin thickness yield shorter half-lives, suggesting a smaller preformation factor. This is quite consistent with the conclusions for even-even a emitters. Moreover, a-decay calculations are extended for odd-mass isomers and superheavy nuclei. The calculated a-decay half-lives are found to be in good agreement with the experimental data.
