Scaling behaviour in cluster decay

A recently proposed scaling law for the decay time of alpha particles is generalized for cluster decay. It is shown that for the decay of even-even parents, log T_1/2 depends linearly on the scaling variable S = (Z_cZ_d)^0.6/√Q_c and on the square root of the reduced mass of cluster and daughter. A model is outlined, which gives insight into the proposed scaling dependence. Predictions of decay modes not yet discovered, such as ¹⁶O, ¹²C and ¹⁵N, are made.
