A new simple model for the alpha decay

We analytically find a new simple alpha-decay formula for a modified harmonic oscillator with the spherical Coulomb potential by employing Wentzel-Kramers-Brillouin approximation in terms of taking into account the Bohr-Sommerfeld quantization condition. We systematically investigate the favored alpha-decay half-lives of 52 <= Z <= 107 alpha-decay half-lives of the parent nuclei.
