The results of a study of central collisions of ^16O nuclei with the heavy elements of nuclear emulsion(^107Ag, ^80Br) at 14.6, 60 and 200 GeV/n are compared with proton-emulsion data at equivalent energy. The multiplicity of produced charged secondaries for the ^16O interactions increases with energy faster than for proton projectiles, but the ratio of the mean meson multiplicity to the number of wounded nucleon is reasonably consistent with the prediction of superposition models. At 200 GeV/n, the central particle pseudorapidity density is found to be 66±2 for events with multiplicities exceeding 200.
