Nuclear Bubble in Sn IsotopeWithin Modified Relativistic Mean Field

Abstract. Nuclear bubble is one of the interesting phenomena in nuclei. Nuclear bubble is characterized by existence of
depletion at the center of nuclei [1, 2]. In this study, we investigated the nuclear bubble phenomena on Sn isotopes by
assuming the corresponding nuclei are spherical. We used Modified Relativistic Mean Field model [3] to describe the
interaction among nucleons in nuclei. It is found that the corresponding depletion near the center of each nucleus density
in Sn isotope is insensitive to the nonlinear isovector parameter variation. In this work, we also study the effects of tensor
and electromagnetic exchange term of the corresponding model on nuclear bubble phenomena on Sn isotopes.
