Abstract

The alpha-decay process is investigated in the presence of the nuclear temperature. Using an analytical approach for the calculation of effective sharp radius and a new barrier potential, the half-lives for the even-even nuclei of Po, Pb, Ra, Rb, Rn, Th and U are derived and compared with the experimental data.
