SOME FEATURES OF INELASTIC INTERACTIONS OF SI-28 AND C-12 IONS IN NUCLEAR-EMULSION AT 4.5A GEV/C

Multiplicity distributions of various types of tracks produced in inelastic interactions of Si-28 and C-12 at 4.5A GeV/c with nuclear emulsion nuclei have been investigated. The correlations of the type [N-i(N-j)] where N-i, N-j = N-g, N-b, N-h Or N-s with i not equal j have been studied and compared with the results from p-Em interactions at the same momentum per nucleon. Some saturation effects in the values of (N-b) with N-g are observed. Furthermore, some of these correlations show almost similar dependence in nucleus-nucleus and proton-nucleus interactions at same per particle momenta. The values of [N-s] have been obtained by subtracting the contribution of Z = 1 fragments to the observed showers. The dependence of [N-s] so obtained on the number of interacting projectile nucleons shows that the nucleus-nucleus collisions at these energies can be interpreted in terms of multiple N-N collisions.
