Multiplicity of secondary particles and fragmentation in nuclear interactions of22Ne and32S nuclei with emulsion at (4.1–4.5)A GeV/c

The interactions of 4.1AGeV/c ²²Ne and 4.5AGeV/c ³²S nuclei with emulsion have been studied and the dependence of the average multiplicities of the emitted secondary charged particles and the interacting projectile nucleons on the impact parameters have been investigated. The behavior of the Koba-Neilsen-Olesen (KNO) scaling formula of the multiplicity distributions produced due to the interactions of²²Ne and³²S at the energies mentioned above is satisfied by all target protons. The multiplicity distributions of the emitted⁴He fragments and the fragmentation cross-section relative to the inelastic cross-section have been investigated and give a⁴He-fragments yield which is always ten times greater than the yield of any other fragments.
