Systematic study of bubble nuclei in relativistic mean field model

Abstract

We have theoretically studied potential bubble nuclei (^20,22O, ^34,36Si, and ⁴⁶Ar), which are experimentally accessible and have attracted several studies in the recent past. Relativistic mean field is employed in conjunction with the NL–SH parameter set. Our results show that among the possible candidates, ²²Oand ³⁴Si may be the most prominent candidates, showing significant depletion of density at the center, which could be verified experimentally in the near future with some of the experiments underway.
