Abstract
Nucleon density distributions in nucleus (including neutron and proton)have been introduced into the Abrasion - Ablation model for the intermediate en ergy collision. Process of projectile fragmentation in the reaction of 30Me V/u (40) Ar + Ag-nat has been simulated with the model of corrected version . The results show that in the rather peripheral collisions there are obvio us differences for the calculated cross sections with and without correctio n of nucleon density distributions in the model. The differences come from the effects of dispersion on the edge of nuclei. It has been verified by co mparison with experimental results that reduction of mean energy of project ile - like fragments from beam energy is mainly caused by the action of fri ction.
