Original Abstract

The emission of alpha particles has been analyzed using a N-14 projectile beam on Co-59, Nb-93, and Au-197 targets at an incident energy of 250 MeV, in the angular range from 8 degrees to 40 degrees. The estimated alpha particles from the break-up channel and the pre-equilibrium mode were compared with the experimentally measured inclusive double differential cross sections at various angles at 250 MeV beam energy. The present results indicate that at such a high incident energy, a significant contribution to the alpha-particle emission comes from direct reactions, which are dominant at forward angles. At larger emission angles, non-equilibrium and evaporation processes increase and compete with direct reactions.
