Abstract

The effect of a Fermi boost and 3 nucleon (3N) collision terms are studied in the framework of the anti-symmetrized molecular dynamics (AMD) of Ono et al. in two extreme cases of intermediate heavy ion collisions, one for the production of high energy nucleons and the other for the hydrogen target with heavier projectiles. The Fermi boost is added in the binary collision process as a fluctuation in the momentum space for colliding two nucleons. The 3N collision term is incorporated using a diagram of three consecutive binary collisions. The model is applied to the available experimental data and the high energy nucleon yields are well reproduced at the incident energy range of 44 A MeV to 400 A MeV. The Fermi boost is effective for the high energy proton production at the incident energy below 50 A MeV. While above 50 A MeV, the 3N collision term becomes dominant. The model is also applied for the proton emission from 12C + 1H at 95 A MeV. The experimental data are also well reproduced by these models.
