摘要：

A set of global optical potentials for alpha particles with energies above 80 MeV has been extended to lower energies and proved appropriate to describe (n, alpha) reactions. It is found that the transmission coefficients for alpha-particle emission are rather strongly related to the fusion cross sections and elastic scattering at energies above 80 MeV, but not to elastic scattering at lower energy where specific features are comprised within complex optical potential parametrizations.
