Calculation of α Decay Half-Lives for Tl, Bi, and At Isotopes

Year: 2025

Type: article

Abstract: We investigated the reaction Q-value (Qα) for the α decay of Tl, Bi, and At isotopes using the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc) with the covariant density functional PC-PK1. The α decay half-lives of Tl, Bi, and At isotopes are evaluated using various empirical formulas, based on both experimental Qα and those obtained from DRHBc calculations. The calculated Qα and α decay half-lives are compared with experimental data. On the basis of these results, we also predicted the α decay half-lives of isotopes for which experimental data are unavailable.
