Abstract
Effects of differences between neutron and proton distributions on 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 -nucleus potentials. In terms of the characteristic of odd-mass emitters, special attention is paid to the decays from ground or isomeric states which end in the ground states of daughter nuclei and furthermore belong to favored 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 emitters. Moreover, -decay calculations are extended for odd-mass isomers and superheavy nuclei. The calculated -decay half-lives are found to be in good agreement with the experimental data.
