Interaction of 4.22-GeV and 7.54-GeVNe20with Cu

The cross sections of 15 products produced in the relativistic heavy-ion reactions of 211 and 377 MeV/nucleon ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ 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 ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$. The target fragmentation yields resulting from peripheral collisions were compared with abrasion-ablation model calculations. Central collision processes were examined by comparing light mass ${}_{}{}^7{}_{}{}^{}\mathrm{Be}$ yields.
