Fragmentation cross sections of 16O, 24Mg, and 32S projectiles at 3.65 GeV/nucleon.

Abstract

We have investigated the fragmentation of 3.65 GeV/nucleon $^{16}\mathrm{O}$, $^{24}\mathrm{Mg}$, and $^{32}\mathrm{S}$ projectiles on C, Al, Cu, Ag, and Pb targets using solid state nuclear track detectors. Track counting was performed by an automatic measuring system. Total charge changing and the partial cross sections for the production of fragments with charges 9\ensuremath{\le}Z\ensuremath{\le}15 for $^{32}\mathrm{S}$ projectiles and of charge 6\ensuremath{\le}Z\ensuremath{\le}11 for $^{24}\mathrm{Mg}$ were determined. Comparison with theoretical models and other experimental data is made.
