Abstract：

The　investigation　of　magic　numbers　for　nuclei　in　the　hyperheavy　region　(Formula　presented.)　is　an　interesting　topic.　The　neutron　magic　number　(Formula　presented.)　is　carefully　validated　by　the　deformed　relativistic　Hartree-Bogoliubov　theory　in　continuum　(DRHBc),　via　analysing　even-even　nuclei　around　(Formula　presented.)　of　the　(Formula　presented.)　isotopes　in　detail.　Nuclei　with　(Formula　presented.)　and　(Formula　presented.)　are　all　found　to　be　spherical　in　their　ground　states.　A　big　drop　of　the　two-neutron　separation　energy　(Formula　presented.)　is　observed　from　(Formula　presented.)　to　(Formula　presented.)　in　the　isotopic　chain　of　(Formula　presented.),　and　a　peak　of　the　two-neutron　gap　(Formula　presented.)　appears　at　(Formula　presented.).　There　exists　a　big　shell　gap　above　(Formula　presented.)　around　the　spherical　regions　of　single-neutron　levels　for　nucleus　with　(Formula　presented.).　These　evidences　from　the　DRHBc　theory　support　(Formula　presented.)　to　be　a　neutron　magic　number　in　the　hyperheavy　region.　©　2024　by　the　authors.
