ResumoThe elastic scattering of 109.2 MeV 3He particles by 40Ca, 58Ni, 90Zr and 116Sn has been investigated over a wide angular range. The elastic scattering cross sections have been analyzed in terms of the optical model. The data for each nucleus studied were sufficient to eliminate the discrete ambiguity in the strength of the optical potential; the unique potential which fits the data has a real well depth of about 100 MeV and a corresponding volume integral per nucleon pair of about 310 MeV · fm3. The elastic scattering of 3He particles by 58Ni has been further measured at bombarding energies of 89.3 and 118.5 MeV, and the incident-energy dependence of the optical potential of 3He particles for 58Ni was obtained.
