CENTRAL COLLISIONS OF SI-28 WITH AG(BR) NUCLEI

This paper presents data on multiplicity and pseudorapidity distributi ons of hadrons from central collisions of Si-28 with Ag(Br) targets at 4.5 GeV/c per nucleon. These events exhibit approximate pseudorapidit y distribution scaling in their target as well as in the projectile re st frames. The average pseudorapidity [eta] is examined as a function of grey particle multiplicity, n(g) and the effect of intranuclear col lisions is discussed. A rough estimation of the energy density has bee n made from the data of this experiment. Also, a comparison with data from collisions induced by lighter nuclei at the same momentum per nuc leon is presented in order to trace the dependence on the projectile m ass.
