The Nucleon Orbital Density Distribution in Isobar

Investigations into the distribution of neutron and proton densities were conducted within the Skyrme-Hartree-Fock-Bogoliubov(SHFB) framework. It was observed that nucleon orbitals with lower angular quantum numbers are predominantly located inside the nucleus, whereas those with higher angular quantum numbers tend to be distributed more towards the outer regions. Additionally, this study reveals that the difference in the neutron skins of Ru and Zr can be attributed to the distinct contributions of neutron and proton orbitals. Our findings may introduce a novel approach to studying the distribution of nucleon orbitals through relativistic isobaric collisions.
