Temperature dependence of the alpha decay half-lives of even-even Th isotopes

Abstract

Using temperature dependent nuclear and Coulomb potentials the temperature dependence of alpha decay half-lives of even-even Th isotopes were analyzed in framework of WKB method with inclusion of quantization conditions. The temperature dependent double-folding and proximity potentials were used in calculations. In temperature independent calculations, in contrary to prox77, very good agreement between calculated half-lives with double-folding and experiment were observed. The obtained results showed the quantization condition, as an essential condition for WKB, caused the elimination of the effect of temperature dependence of prox77. Considering temperature dependent potentials and Q-value decreasing behavior of half-life with temperature was observed.
