Experimental data on multiplicities and correlations of charged particles of different types produced in collisions of 4.5 A GeV/c carbon-12 with emulsion are reported and discussed. The data are compared with the results of other experiments on nucleus–nucleus and hadron–nucleus collisions. It is found that the particle production mechanism in nucleus–nucleus collisions is almost the same as in hadron–nucleus collisions. It is also observed that the shower particles' multiplicity distributions obey a KNO type scaling law, which supports the aforementioned result.

A detailed study of the mechanism of emission of pions and protons in the forward and backward hemispheres in 4.5A GeV/c silicon-emulsion interactions has been carried out. For this purpose, a random sample comprising 1024 interactions caused by silicon nuclei is analyzed to examine the behavior of the emission characteristics of pions and protons emitted in the forward and backward hemispheres. The values of the forward-backward ratio and the asymmetry parameter as a function of the number of heavily ionizing particles are determined. The behavior of the angular distributions of pions and protons in the backward hemisphere and multiplicity correlations is also investigated. The results yield quite interesting information regarding the mechanism of production of pions and protons in the backward hemisphere.

MULTIPLICITY CHARACTERISTICS OF HEAVY ION INTERACTIONS AT 4.5-GEV/C PER NUCLEON

This paper presents exhaustive, new data on the shower and compound multiplicity charactersties of 24 Mg-emulsion and 12 C-emulsion interactions at incident momentum of 4.5 GeV/ c per nucleon. A comparative study is made (whenever possible) with p-emulsion interaction data at the same incident momentum per nucleon. The linear dependences of different multplicities on shower and compound multiplicity, e.g., 〈 n i 〉 = a ij + k ij n j -( i ≠ j ), are also shown in this paper.
