α-Particle induced reactions on rhodium

摘要

Excitation functions for ~(103)Rh (α, xn); x = 1 - 4 and ~(103)Rh (α, αxn); x = 1 - 3 reactions were measured up to 50 MeV bombarding energy using stacked foil activation technique and high purity germanium (HPGe) γ-ray spectroscopy method. The experimental results were compared with calculations considering equilibrium as well as pre-equilibrium hybrid model of Blann (ALICE/90). It is found that the initial exciton configuration n_0 = 4(4p0h) gives fairly good agreements for (α, xn) reactions. There seems to be indication of direct inelastic scattering effects in (α, αxn)-type of reactions.
