Systematic study of α-decay half-lives for Pa isotopes using MGLDM model

Abstract

The [Formula: see text]-decay half-lives for odd [Formula: see text] Pa isotopes were estimated by using the modified generalized liquid drop model (MGLDM) in the neutron number range [Formula: see text]. These half-lives are found to be an excellent match with available experimental data certified by the least root mean-square error when compared with the other recently proposed empirical formulas. The applicability of MGLDM is proved on the odd [Formula: see text]-odd [Formula: see text] (even [Formula: see text]) nuclei in a successful manner in describing their [Formula: see text]-decay half-lives which are employed to predict half-lives of few unknown Pa isotopes. Our results are expected to provide more extensive and precise information of half-lives for the upcoming experiments eyeing on the boundaries of the trans-led nuclei.
