Abstract
We have investigated the interactions of 10.6GeV/n Au in nuclear emulsion.
Two methods of separating interactions into those with hydrogen,
light (C,N,O)and heavy (Ag,Br) target nuclei were used, giving almost
identical results, which strengthened our confidence in the correctness of
these methods. We also measured the angular distributions of singly and
multiply charged relativistic particles emitted from the interaction
vertices and the charges of the multiply charged projectile fragments. The
fragmentation of the projectile Au nuclei and of the target nuclei were
analyzed. The multiparticle production was studied as a function of
the mass of the target nucleus. The multiplicity and the
pseudorapidity distributions of relativistic singly charged particles were
compared with the predictions of the RQMD Model.
