Physical review letters, 2011•APSA benchmark experiment on Pb 208 shows that polarized proton inelastic scattering at very
forward angles including 0° is a powerful tool for high-resolution studies of electric dipole (E
1) and spin magnetic dipole (M 1) modes in nuclei over a broad excitation energy range to
test up-to-date nuclear models. The extracted E 1 polarizability leads to a neutron skin

A benchmark experiment on shows that polarized proton inelastic scattering at very forward angles including 0° is a powerful tool for high-resolution studies of electric dipole () and spin magnetic dipole () modes in nuclei over a broad excitation energy range to test up-to-date nuclear models. The extracted polarizability leads to a neutron skin thickness in derived within a mean-field model [Phys. Rev. C 81, 051303 (2010)PRVCAN0556-281310.1103/PhysRevC.81.051303], thereby constraining the symmetry energy and its density dependence relevant to the description of neutron stars.
