Abstract
Cross sections and analyzing powers for polarized proton elastic scattering from , and were measured at intermediate energy MeV. An effective relativistic Love-Franey interaction is tuned to reproduce scattering data within the framework of the relativistic impulse approximation. The neutron densities of the lead isotopes are deduced using model-independent sum-of-Gaussians distributions. Their error envelopes are estimated by a new criterion including uncertainties associated with the reaction model. The systematic behaviors of extracted error envelopes of the neutron density distributions in are presented. The extracted neutron and proton density distribution of gives a neutron skin thickness of fm.
