Alpha decay half-lives of even-even nuclei using alpha-folding interaction

The alpha decay half-lives of some even-even nuclei have been calculated using WKB method and including Bohr-Sommerfeld quantization for nuclear potential. Three forms of the nucleon-nucleon, alpha-nucleon, and alpha-alpha folding potentials have been adopted for calculation of the nuclear potential. Moreover, the phenomenological two parameter Fermi (2pF) and the microscopic Hartree-Fock-Bogoliubov (HFB) density distributions have been employed for nuclear matter. The effect of the folding potentials and matter densities have been investigated. The obtained results showed good agreement between theory and experiment and confirmed the applicability of the alpha-folding potentials in alpha decay calculations.
