Optical model analyses of heavy ion fragmentation in hydrogen targets.
Quantum-mechanical optical-model methods for calculating cross sections for the fragmentation of high-energy heavy ions by hydrogen targets are presented.  The cross sections are calculated with a knockout-ablation collision formalism which has no arbitrary fitting parameters.  Predictions of elemental production cross sections from the fragmentation of 1.2A GeV 139La nuclei and of isotope production cross sections from the fragmentation of 400A MeV 32S nuclei are in good agreement with recently reported experimental measurements.
