| Abstract: | The phenomenon of proton decay is treated as the transmission of the proton across a potential barrier developed due to combined effects of the Coulomb potential, centrifugal potential and various renormalization processes. In the present paper, a microscopic approach has been used to calculate a Coulomb potential from Woods-Saxon charge density distribution function. Half-lives of proton emitters have been calculated in the framework of WKB method with modified Coulomb potential. Significant improvement in the values of half-lives is obtained as compared to those calculated with the Coulomb potential of a spherical charged core. |
