Calculation of proton radioactivity half-lives

We have investigated the proton radioactivity half-lives of 45 proton emitters within the framework of the Wentzel-Kramers-Brillouin (WKB) method by considering the Bohr-Sommerfeld quantization condition. The orientation angle dependent Woods-Saxon, Coulomb, and spin-orbit potentials and centrifugal potential have been used in calculations. We observed that using the orientation angle dependent formalism decreases the values of calculated half-lives.
