Simple optical model treatment of the elastic 3He scattering

The elastic scattering of 3He from nuclei in the mass range AT=10-208 at projectile energies from 10 MeV to 220 MeV is analyzed in the frame of the simple optical model. An empirical parametrisation of the central potential for the whole mass and energy range is given that satisfies all qualitative requirements put on optical potentials by the theories. The discrete ambiguity is phenomenologically resolved by the parametrization presented in this work. (orig.)
