Theoretical a-decay half-lives of some nuclei from ground state to ground state are calculated using different nuclear potential model including Coulomb proximity potential (CPPM), Royer proximity potential and Broglia and Winther 1991. The calculated values comparing with experimental data, it is observed that the CPPM model is in good agreement with the experimental data. | a-decay half-lives of some nuclei from ground state to ground state using different nuclear potential EPJ Nuclear Sci.
