Alpha-decay properties of nuclei around neutron magic numbers∗

Extracted $\alpha$-particle preformation factors and calculated half-lives for nuclei around neutron magic number $N$ of 126 . The experimental $\alpha$-decay energies and half-lives were retrieved from $$\text { www. nndc. bnl. gov }$$. The decay energies and half-lives were measured in megaelectron-volts and seconds, respectively.
