# Nuclear "bubble" structure in $^{34}$Si

Abstract : Bubble nuclei are characterized by a depletion of their central density. Their existence is examined within three different theoretical frameworks: the shell model and nonrelativistic and relativistic microscopic mean-field approaches.We analyze 34Si and 22O as possible candidates for proton and neutron bubble nuclei, respectively. In the case of 22O, we observe a significant model dependence, thereby calling into question the bubble structure of 22O. In contrast, an overall agreement among the models is obtained for 34Si. Indeed, all models predict a central proton density depletion of about 40% and a central charge density depletion of 25%-30%. This result provides strong evidence in favor of a proton bubble in 34Si.
