Abstract
Recently measured data for elastic scattering angular distributions of He-6,He-8 projectiles on a Cu-65 target at three energies above the Coulomb barrier (19.9, 22.6 and 30.6 MeV) have been investigated in the framework of the optical model potential. The real parts are microscopically calculated with the Reid M3Y effective nucleon-nucleon interaction by using the double folding approach. Results comparable to the experimental data were obtained using two different forms of the imaginary part. The total reaction cross sections were successfully reproduced using the extracted potentials.
