Relativistic heavy ion collisions may be classified as central (and near central), peripheral, and grazing with each collision type producing different proton and other charged projectile fragment scattering mechanisms and characteristics. This report focuses on peripheral and grazing collisions in the fragmentation of Carbon-12 into Boron-11 and a proton, testing models of the kinetics involved in this reaction. The data were measured at the Heavy Ion Superconducting Spectrometer (HISS) at Lawrence Berkeley Laboratory and include excitation energy for the p/Boron-11 pair, and rapidity versus transverse momentum for protons and Boron-11. 58 refs., 35 figs., 8 tabs. (DWL).

The production of charged nuclear fragments was measured in collisions of 0.93 GeV/c/nucleon, 1.75 GeV/c/nucleon, and 2.88 GeV/c/nucleon alpha particles on targets of carbon, copper, lead, and CH2, using a double focusing spectrometer. Single particle inclusive cross sections are then presented for the production of protons, deuterons, tritons, 3He, and 4He at momenta from 0.5 to 11.5 GeV/c and angles from 0 to 12°. The relevance of the concept of limiting fragmentation to data is discussed and possible uses of the data to study nuclear structure and particle production mechanisms are pointed out.
