Multiplicity Distributions in Pseudorapidity Intervals withS32at 200 GeV/nucleon andO16at 200 and 60 GeV/nucleon

We present results of our systematic studies of charged-shower-particle multiplicities and their dependence on pseudorapidity intervals for nearly central events produced by ${}_{}{}^{32}{}_{}{}^{}\mathrm{S}$ at 200 GeV/nucleon and ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ at 200 and 60 GeV/nucleon in nuclear emulsion. An increase in the particle density with the increase of particle energy and mass is observed. We find an energy-independent linear relation between the maximum particle density (in a given pseudorapidity interval) and shower-particle multiplicity.
