摘要：

In the present work, we intended to study the alpha-decay half-lives of the even-even nuclei from Po-178 to Ra-226 in ground state. We investigated a semi-empirical, one-parameter model based on tunneling through a potential barrier with the centrifugal and overlapping effects. Half-lives of alpha-decay of even-even nuclei calculated by using different versions of proximity potentials (gpp77, MCW76 and MB77) are compared to experimental data. Also, the computed half-lives are compared with the Royer formula, Akrawy and Poenaru (AKRE) formula, modify Ren (MRen B) formula and Denisov-Khudenko (DEKH) formula and with the experimental data. The results are in good agreement with the experimental data.
