摘要
The nuclear a decay of heavy nuclei is investigated based on the nuclear energy density functional, which leads to the a potential inside the parent nucleus in terms of the proton and neutron density profiles of the daughter nucleus. We use the Skyrme force model, Gogny force model, and relativistic mean-field model to get the nucleon density profiles inside heavy nuclei. Once the nucleon density profiles are determined, the parameters of the nuclear a potential are fitted to the observed a decay half-lives of heavy nuclei. This approach is then applied to predict unknown a decay half-lives of heavy nuclei. To estimate the Q values of unobserved a decays, we make use of the liquid droplet model.
