α-Decay: A distinct type of spontaneous fission
With the help of a plot of logarithmic experimental α-decay half-life of even-even α-emitters versus the fissility parameter, it is demonstrated that α-decay is a distinct type of spontaneous fission. A simple empirical relation between experimental α-decay half-life and the fissility parameter is also given. A close examination of the nature of dependence of α-decay half-life on fissility parameter reveals that Coulomb repulsive energy accelerates the process of α-decay rather than retard it.
