Measuring the surface thickness of the weak charge density of nuclei

NUCLEAR REACTIONS ⁴⁸Ca, ²⁰⁸Pb(polarized e^-, e^-), E=855, 950, 2220 MeV; calculated differential σ(θ) and parity violating asymmetry including Coulomb distortions, radius and surface thickness parameters, weak charge density versus radius for 855 MeV beam energy, log derivative of parity violating asymmetry with respect to the log of the surface thickness parameter or the log of the weak radius versus scattering angle; evaluated statistical uncertainties and figure of merit (FOM) for proposed experiments at the A1 spectrometer facility of the MAMI accelerator to measure the surface thickness of the weak charge density of a heavy nucleus, further to present PREX-II and CREX parity violating electron scattering experiments probing the weak charge densities. Fermi function fit with relativistic and non-relativistic mean field models.
