Abstract

The intermediate energy (p,p x) reaction is studied with antisymmetrized molecular dynamics (AMD) in the cases of Ni58 target with Ep=120 MeV and C12 target with Ep=200 and 90 MeV. Angular distributions for various Ep energies are shown to be reproduced well without any adjustable parameter, which shows the reliability and usefulness of AMD in describing light-ion reactions. Detailed analyses of the calculations are made in the case of Ni58 target and the following results are obtained: Two-step contributions are found to be dominant in some large angle region and to be indispensable for the reproduction of data. Furthermore, the reproduction of data in the large angle region 120°for Ep=100 MeV is shown to be due to three-step contributions. Angular distributions for Ep 40 MeV are found to be insensitive to the choice of different in-medium nucleon-nucleon cross sections NN and the reason for this insensitivity is discussed in detail. On the other hand, the total reaction cross section and the cross section of evaporated protons are found to be sensitive to NN. In the course of the analyses of the calculations, comparison is made with the distorted wave approach.
