In this work, we systematically study the α decay half-lives of 196 even-even nuclei using a two-potential approach improved by considering nuclear deformation. The results show that the accuracy of this model has been improved after considering nuclear deformation. In addition, we extend this model to predict the α decay half-lives of Z = 118 and 120 isotopes by inputting the α decay energies extracted from the Weizsacker-Skyrme-type (WS-type) mass model, a simple nuclear mass formula, relativistic continuum Hartree-Bogoliubov theory and Du...
