Universal decay law for α-decay with screening correction
A new empirical formula for the α-decay half-lives is obtained from the generalization of the electrostatic interaction with the inclusion of a screening effect [1, 2]. The screening is modeled through the analytical form of the Hulthen potential. The obtained formula recovers the universal decay law when screening is absent. Numerical applications [3,4,5] are performed for the assertion of the impact of the screening effect on the reproduction of data for heavy and superheavy nuclei and for generating predictions for exotic nuclei.
