The fragmentation cross sections of relativistic krypton, xenon, holmium and gold nuclei in targets of aluminium, carbon and polyethylene were measured. The beams were accelerated to maximum rigidity at the LBL Bevalac, corresponding to energies per nucleon of 1.5, 1.2, 1.1, and 1.0 Gev/amu for Kr, Xe, Ho, and Au respectively. The total and partial charge changing cross sections were determined for each beam and target combination, and cross sections in hydrogen were derived from the polyethylene (CH/sub 2/) and carbon data. The total cross sections were found to be 10% to 15% smaller than the predictions of a formula derived from measurements made with lower charge nuclei, and a new representation of the dependence of the total charge changing cross sections on beam and target charge was determined.
