Central collisions of 14.6, 60, and 200 GeV/nucleonO16nuclei in nuclear emulsion

Abstract

Central collisions of ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ nuclei with the ${}_{}{}^{107}{}_{}{}^{}\mathrm{Ag}$ and ${}_{}{}^{80}{}_{}{}^{}\mathrm{Br}$ nuclei in nuclear emulsion at 14.6, 60, and 200 GeV/nucleon are compared with proton-emulsion data at equivalent energies. The multiplicities of produced charged secondaries are consistent with the predictions of superposition models. At 200 GeV/nucleon the central particle pseudorapidity density is 58±2 for those events with multiplicities exceeding 200 particles.
