Abstract
A nonlocal dispersive-optical-model analysis has been carried out for neutrons and protons in 48Ca and 208Pb. Elastic-scattering angular distributions, total and reaction cross sections, single-particle energies, the neutron and proton numbers, and the charge distribution have been fitted to extract the neutron and proton self-energies both above and below the Fermi energy. Charge and neutron matter distributions in 48Ca and 208Pb are determined from these self-energies. Best fit neutron skins of 0.249 ± 0.023 fm and 0.25 ± 0.05 fm are deduced in 48Ca and 208Pb, respectively. The energy dependence of the total neutron cross sections is shown to have strong sensitivity to the skin thickness.
