Has a Thick Neutron Skin in 208Pb Been Ruled Out?

The Lead Radius Experiment has provided the first model-independent evidence in favor of a neutron-rich skin in Pb-208. Although the error bars are large, the reported large central value of 0.33 fm is particularly intriguing. To test whether such a thick neutron skin in Pb-208 is already incompatible with laboratory experiments or astrophysical observations, we employ relativistic models with neutron-skin thickness in Pb-208 ranging from 0.16 to 0.33 fm to compute ground-state properties of finite nuclei, their collective monopole and dipole response, and mass-versus-radius relations for neutron stars. No compelling reason was found to rule out models with large neutron skins in Pb-208 from the set of observables considered in this Letter.
