Microscopic abrasion-ablation approximation to projectile fragmentation
- National Superconducting Cyclotron Laboratory, Michigan State University, East Lansing, Michigan 48824 (United States)
This microscopic abrasion-ablation model approximates primary fragment cross sections using the Glauber interaction probabilities of the individual nucleon orbitals. It estimates the excitation energy distribution of the primary fragments using the density of hole states left by the abraded nucleons. The secondary (observable) cross sections are obtained by taking into account the statistical decay of each primary fragment over its entire range of excitation energy. The agreement with experimental data is good for light projectiles but deteriorates with increasing mass of the projectile, due to the increasing importance of secondary collisions of the abraded nucleons with the rest of the projectile.
