The ablation stage in the fast abrasion model

Abstract

In order to verify the effect of the ablation stage on the fast abrasion mechanism, detailed evaporative calculations have been performed on the primary projectile and target-like fragments issued from the reactions 4~ + aTA1 and 4~ + 27A1. The results account for many of the experimental features observed in the projectile and target-like fragments produced at intermediate energies. However it is pointed out that, in order to get a better agreement between theory and experimental data, the primary projectile and target-like fragments should carry a more substantial excitation energy than predicted by a purely geometric abrasion model.

Fission of Relativistic Nuclei with Fragment Excitation and Reorientation

“…The excitation needed iss two to three times larger than that obtained in the original abrasion-ablation model [11][12][13]. Using this trick the agreement with the experimental data is surprisingly good [12,29]. We show that this multiplication factor might not be needed, at least of the reactions involving heavy nuclear targets.…”
