Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Science - Department of Physics Summary: In 3.7A GeV ¹⁶O interactions with emulsion nuclei, the inelastic interaction cross section of ¹⁶O in nuclear emulsion is approximated as a function of the target mass number. In the present energy region, the cross section is independent on the energy. It can be determined in the light of the Glauber's multiple scattering theory. The multiplicity characteristics of shower particles produced in 3.7A GeV ¹⁶O interactions with emulsion nuclei are studied. The effect of the projectile and target sizes on the shower particles production is examined. The produced shower particles are discriminated into forward ones that produced in the forward angular zone (FHS) and the backward ones that produced in the backward angular zone (BHS). The interaction probability with each target nuclei (H, CNO, Em, and AgBr) is simulated on the basis of Glauber's multiple scattering theory approaches. The forward emitted shower particles multiplicity distributions are usually characterized by Poisson peaking shapes, which imply multisource superposition. These sources depend on the system size, centrality, and incident energy. Therefore these particles can originate from fireball nuclear matter or hadronic nuclear matter. The backward emitted shower particles multiplicity distributions are usually characterized by decay shape. However, this shape can deform to shoulder shape at higher centralities. The multiplicity characteristics depend only on the target size regarding the limiting fragmentation hyposises at Elab ~ 3-4 GeV and projectile mass number {u2265} 6. The results indicate that a single target source is mainly responsible for shower particles creations. Particle production and other secondary source can be contributed at higher centralities
