Elastic proton scattering

The radial shape of the nuclear density distribution of exotic nuclei may be extracted from high-energy proton elastic scattering in inverse kinematics. Previous measurements [1] using secondary beams at 700 MeV/nucleon have demonstrated the power of the method to investigate halo and skin structures in nuclei far off stability. Complementary to the experiments proposed at the storage ring, elastic scattering will be measured at R³B using (thick) liquid hydrogen or frozen hydrogen targets, and focusing on larger momentum transfer and very short-lived nuclei, which are produced with low intensity only.
