摘要：

A numerical code to evaluate the half-lives for alpha decay, cluster radioactivity and cold fission processes for a given parent nucleus is presented, The Gamow penetrability factor is obtained by considering the pre-scission phase of two intersecting spheres in the effective one-dimensional barrier potential, Two inertia coefficients and two different modes for the shape parametrization are implemented in order to discuss the effect of the inertia coefficient on the half-lives of the spontaneous processes under study.
