Density dependence of the nuclear symmetry energy and neutron skin thickness in the KIDS framework

The KIDS framework for the nuclear equation of state (EoS) and energy density functional (EDF) offers possibility to explore systematically effect EoS parameters on predictions a variety observables. can be varied independently each other assumptions regarding in-medium nucleon effective mass. Here I present pilot study neutron skin thickness (NST) in nuclei current interest. results indicate that variations symmetry slope parameter L by roughly 10 MeV droplet-model counterpart curvature K? 20 affect comparable amounts. However, structural details may also have sizable effects predictions, notably cases 68Ni 208Pb. This work is part systematic investigation NST within broader effort constrain dependence energy.
