In order to predict heavy particle radioactivities in 1980 and to arrive at a unified approach of cluster decay modes, alpha disintegration, and cold fission, before the first experimental confirmation3 in 1984, we developed and used a series of fission theories in a wide range of mass asymmetry, namely: fragmentation theory, numerical (NuSAF) and analytical (ASAF) superasymmetric fission models, and a semiempirical formula for a-decay (see the multiauthored book * and the references therein).
