The multiplicity and correlations of the forward ( θ<90o ) and backward ( θ≥90o ) secondary particles emitted in 22 Neand 28 Si-emulsion interactions are calculated according to the modified cascade and modified Fritiof models. The predictions of the two models are compared with experimental data at incident momentum of ( 4.1-4.5 ) GeV/c per nucleon. Both models depend on the Monte Carlo techniques where the modified cascade model implies the superposition of nucleon-nucleon interactions, and the modified Fritiof model utilizes the Regge theory for the description of the cascading process. Comparison with data shows no clear preference of one model over the other. However, the modified Fritiof model seems to be nearer to the experimental data than the modified cascade model, which appear to overestimate the number of the intranuclear cascade.
