Shrunk halo and quenched shell gap at $N=16$ in ${}^{22}$C: Inversion of $sd$ states and deformation effects

Xiang-Xiang Sun, Jie Zhao, Shan-Gui Zhou

We investigate the ground state properties of ${}^{22}$C by using a deformed relativistic Hartree-Bogoliubov model in continuum and explore the interplays among the formation of a ha…
