摘要：

An analysis of all available alpha-particle-induced reaction cross sections on nuclei within the mass number range 121 <= A <= 197, below the Coulomb barrier, is carried out. This analysis leads to an optical potential that describes the alpha-particle elastic scattering at low energies as well and both elastic-scattering and reaction data for 45 <= A <= 124. The energy dependence of the surface imaginary potential depth is proved to be essential for understanding alpha-particle interaction behavior below the Coulomb barrier.
