| Abstract | ||
| Different transition rates of the nuclear preequilibrium states in the exciton model were numerically calculated in the present work, as well as the state density and matrix element of the nuclear interaction. The calculations were based on the two-component version of the exciton model. Some comparisons were made with earlier calculations, and the results showed a good agreement. The results were explained on the bases of the effects of the differences in the particle and hole numbers, as well as the type of the incident particle and its energy. The conclusions indicated that preequilibrium nuclear reactions induced by protons differ only by small fraction from those induced by neurons at low exciton states. At higher exciton states with n>3, the transitions of the types and differed significantly between neutron and proton transitions, which may indicate distinguishable nuclear reaction mechanisms. | ||
