Abstract

Cluster radioactivities of nuclei far from beta-stability line in the neutron-rich region, where a-decay is not allowed, have been systematically studied within analytical superasymmetric fission model. Input mass tables calculated by various authors were used to determine the released energy. Half-lives shorter than 1030 seconds have been estimated for very neutron-rich parent nuclei with atomic numbers form 57 to 86. The emitted clusters are also proton-deficient nuclei, as for example 22O, 46S, 50Ar, 76Fe, 78Ni, etc.
