Reexamining the neutron skin thickness within a density dependent hadronic model

Abstract

We calculate the skin thickness, binding energy, surface energy and density profiles within the Dirac solution of a density dependent hadronic model and compare with the NL3 parametrization results of the non-linear Wallecka model. The asymmetry for polarized electron scattering is also obtained using a partial wave expansion calculation. Results for 208Pb, 40Ca, 48Ca, 66Ni and 90Zr are shown and discussed.Comment: 7 pages, 6 figures and 2 tables. Accepted for publication in Physical Review
