A Comparative Study of Proton-Emulsion and Heavy-Ion-Emulsion Interactions at 4.5 GeV/c per Nucleon

This paper presents a comparative study of inelastic interactions of proton-Emulsion, ¹²C-Emulsion and ²⁴Mg-Emulsion at 4.5 GeV/c per nucleon. The multiplicity distribution and their correlations have been studied. A strong correlation between 〈n_s〉 and n_h in case of ²⁴Mg-Emulsion and ¹²C-Emulsion is observed which is not so in the case of proton-Emulsion interaction. It is also observed that 〈n_s〉 increases with the increase of the projectile mass. The angular distribution of the target fragments in ²⁴Mg-Emulsion and ¹²C-Emulsion interactions show massive forward collimations. Comparison is also made in the pseudorapidity distributions of ²⁴Mg-Emulsion, ¹²C-Emulsion and proton-Emulsion interactions. The result shows many interesting features.
