Complete mass distributions of the energetically allowed decays of nuclei with A > 112 were calculated including the known regions of cluster radioactivity and cold fission. These processes represent different branches of the more general family of cold decays. A short review of the current experimental situation is given. The existing data indicate that the transition between the sudden (α-decay-like) and adiabatic (fission-like) mechanisms of the fragments formation takes place at the fragments mass values A ∼ 35–40. The study of elastic scattering or fusion-fission reaction of the decay products could serve as a sensitive tool for investigation of the decay mechanism. Some new experiments to be carried out and planned are listed.
