Abstract

Fission- (FM) and preformation cluster- (PCM) models are reviewed, pointing out the differences between the adopted nuclear radii, zero point vibration energies, potential barriers, and the methods of calculating the half-lives. FM are equivalent with PCM because cluster preformation probability is the penetrability of the prescission part of the barrier. A universal curve for each type of cluster radioactivity is derived. The analytical superasymmetric FM shape parametrization is the optimum fission path for clusters with mass numbers smaller than 34. The influence of a smooth neck (in a two dimensional fission dynamics) is important for symmetric and lowasymmetric fission.
