Effective liquid drop description for alpha decay of atomic nuclei

Abstract

Alpha-decay half-lives are presented in the framework of an effective liquid drop model for different combinations of mass transfer descriptions and inertia coefficients. Calculated half-life values for ground-state-ground-state-favoured alpha transitions are compared with available, updated experimental data. Results have shown that the present model is very suitable to treat the alpha-decay process on an equal footing as cluster radioactivity and cold fission processes. Better agreement with the data is found when the subset of even-even alpha emitters is considered in the calculation.
