Abstract

A simple phenomenological model based on the Gamow theory for the evaluation of half-lives for $α$ and cluster radioactivity is proposed. The model contains only one adjustable parameter: the nuclear radius constant, common for both kind of decays and an additional hindrance factor to the lifetimes which gives the effect of an odd particle. A good agreement with the experimental data for nuclei with $Z \geq 84$ and $N \geq 104$ is achieved.
