Release of Nuclei from Relativistic Nucleus-Nucleus Interactions

Abstract

We have examined relativistic nuclei of iron, krypton, xenon, holmium and gold, accelerated to maximum rigidity at the LBL Bevalac, interacting with targets of aluminum, carbon and polyethylene. For each projc*:tile and target combination we determined the total and partial charge changing cross-sections. From these measurements we have developed a new representation of the dependence of the total charge changing cross-sections on beam and target charge. We have also identified simple representations of the variation of the partial cross-sections with the charge of the produced fragments and shown that they are dependent on the charge and energy of the beam.
