Abstract
An analysis of all available -particle-induced reaction cross sections on nuclei within the mass number range , below the Coulomb barrier, is carried out. This analysis leads to an optical potential that describes the -particle elastic scattering at low energies as well and both elastic-scattering and reaction data for . The energy dependence of the surface imaginary potential depth is proved to be essential for understanding -particle interaction behavior below the Coulomb barrier.
