Possible existence of bound nuclei beyond neutron drip lines driven by deformation

Based on the relativistic calculations of the nuclear masses in the transfermium region from No \begin{document}$ (Z = 102) $\end{document} to Ds \begin{document}$ (Z = 110) $\end{document} using the deformed relativistic Hartree-Bogoliubov theory in continuum (DRHBc), the possible existence of bound nuclei beyond the neutron drip lines is studied. The two-neutron and multi-neutron emission bound nuclei beyond the primary neutron drip line of \begin{document}$ N = 258 $\end{document} are predicted in \begin{document}$ Z = 106,108 $\end{document} , and \begin{document}$ 110 $\end{document} isotopes. A detailed microscopic mechanism investigation reveals that nuclear deformation plays a vital role in the existence of bound nuclei beyond the drip line. Furthermore, not only the quadrupole deformation \begin{document}$ \beta_{2} $\end{document} but also the higher orders of deformation are indispensable in the reliable description of the phenomenon of reentrant binding.
