Systematic study of the $\alpha$ decay preformation factor of nuclei around the $\mathbf{Z}=82$, $\mathbf{N}=126$ shell closures within a generalized liquid drop model

In this work, we systematically study the $\alpha$ decay preformation factors $P_{\alpha }$ and $\alpha$ decay half-lives of 152 nuclei around $Z$ = 82, $N$ = 126 closed shells based on a generalize…
