Theoretical study on favored alpha-decay half-lives of deformed nuclei

A systematic study on $\alpha$-decay half-lives for the nuclei in range $93\leq Z \leq 118$ is done by employing various versions of proximity potentials. To obtain more reliable results, deformation terms are included up to hexadecapole ($\beta_{4}$) spherical-deformed nuclear and Coulomb interaction The favored $\alpha$-decays process this region categorized as even-even, odd A, odd-odd nuclei, first, second they grouped into two parts a ground state isomeric states transition. Due their root-mean-square deviations (RMSD's) comparison, $Bass 77$ $Ngo 80$ have least values better compromise reproducing experimental data. Besides, considering preformation probability within cluster formation model, results validate that significant reduction has been obtained different proximity; Hence detract deviation between calculated
