© 2022 Jagellonian University. All rights reserved.We systematically examine the alpha decay half-lives of 80 superheavy nuclei (SHN) with 104 ≤ Z ≤ 118 employing the new analytical formula, which is obtained using the semi-classical Wentzel-Kramers-Brillouin (WKB) approximation within the framework of the alpha cluster model for the modified harmonic oscillator and spherical Coulomb potentials. We develop an empirical formula for the depth of the nuclear potential that satisfactorily describes the experimental data, and compare our results with the universal decay law (UDL), Royer formula, and the effective liquid drop model (ELDM) described in the literature. Relying on our model, which successfully explains the alpha decay half-lives of the synthesized superheavy nuclei, we predict the alpha decay half-lives of 101 superheavy nuclei with 104 ≤ Z ≤ 120, whose experimental alpha decay half-lives are unknown, and compare the results with UDL, Royer, and ELDM models. The variation of the alpha decay half-lives of these models as a function of the neutron number exhibits the shell closure effect at N = 178 and N = 184.
