Abstract

The cross sections of 15 products produced in the relativistic heavy-ion reactions of 211 and 377 MeV/nucleon Ne20 ions with Cu were measured using activation techniques. The isobaric mass yield curves measured in this study compare well with previous results of relativistic heavy-ion- and proton-induced Cu spallation after taking into account the increased absolute total reaction cross section of Ne20. The target fragmentation yields resulting from peripheral collisions were compared with abrasion-ablation model calculations. Central collision processes were examined by comparing light mass Be7 yields.

NUCLEAR REACTIONS Cu(Ne20, spallation), E=4.22 and 7.54 GeV. Measured absolute σ(A, z) 15 products, deduced mass yield. Natural targets Ge(Li) γ-ray spectroscopy.
