- The calculation of the isotopic production cross sections from high-energy heavy-ion reactions has proceeded along two divergent paths. From the regime of relativistic heavy-ion reactions comes the abrasion--ablation model, which is dependent on the quick nature of these collisions and the separation of the reactant nuclei into participants and spectators. From the intermediate energy regime comes the intranuclear cascade model, where the reaction is treated as a sum of nucleon--nucleon scattering events inside a nuclear potential well. Both frameworks are able to treat projectile as well as target fragmentation. In this report the results of both model calculations are compared with recent experimental data for the fragmenta--ion of 213-MeV/A /sup 40/Ar projectiles by /sup 12/C nuclei and for the fragmentation of /sup 209/Bi target nuclei by a 400-MeV/A /sup 20/Ne beam. These comparisons show the importance of the statistical decay process in determining the distribution of final products as well as the deficiencies of the two models. 3 figures.
