Reexamining the neutron skin thickness within a density dependent hadronic model

TL;DR

This paper compares neutron skin thickness and related nuclear properties calculated using a density dependent hadronic model with those from the NL3 parametrization, including implications for polarized electron scattering.

Contribution

It introduces a density dependent hadronic model for calculating nuclear skin thickness and compares its results with established NL3 model predictions.

Findings

Consistent neutron skin thickness results for multiple nuclei.

Differences observed between models in surface energy and density profiles.

Implications for polarized electron scattering measurements.

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.
