Abstract

We propose a practical folding model to describe He3 elastic scattering. In the model, He3 optical potentials are constructed by making the folding procedure twice. First the nucleon-target potential is evaluated by folding the Melbourne g matrix with the target density and localizing the nonlocal folding potential with the Brieva-Rook method, and second the resulting local nucleon-target potential is folded with the He3 density. This double single-folding model well describes He3 elastic scattering from Ni58 and Pb208 targets in a wide incident-energy range from 30 to 150 MeV/nucleon with no adjustable parameter. Spin-orbit force effects on differential cross sections are found to be appreciable only at higher incident energies such as 150 MeV/nucleon. Three-nucleon breakup effects of He3 are investigated with the continuum discretized coupled-channels method and are found to be appreciable only at lower incident energies around 40 MeV/nucleon. Effects of knock-on exchange processes are also analyzed.
