摘      要：The neutron shell gap at N=152 has been experimentally confirmed through high-precision mass measurements on nobelium(Z=102)and lawrencium(Z=103)*** experimental measurements onα-decay properties suggest that deformed doubly-magic nature of ^(270)***,the magic gaps in the superheavy region are generally expected to be *** this study,we test the robustness of N=152 shell closure in N=152 isotones and Z=108 shell closure in Hs isotopes by employing an alternative approach where both theoretical analysis and available experimental data are *** with existing experimental measurements on a-decay energies,it is determined that robust N=152 neutron shell persists at least in Z=101-105 isotopes,and robust Z=108 proton shell persists in Hs isotopes with N=159,***,the relativistic mean-field model is determined as unable to provide N=152 ***,the conclusion that robust N=152 shell exists at least in Z=101-105 isotopes,provides crucial benchmarks for constraining effective interactions suitable for superheavy nuclei in nuclear energy-density functional theory in future.
