SYSTEMATIC COMPARISON OF THE EXPERIMENTAL DATA WITH THE FRITIOF MODEL IN NUCLEUS–NUCLEUS INTERACTIONS WITH LIGHT AND HEAVY TARGET NUCLEI IN NUCLEAR EMULSION AT 4.5A Gev/c

Abstract

The characteristics of the interactions of 4.5 A GeV/c 28 Si nuclei with emulsion have been investigated. The method of separating interactions into those with hydrogen, light and heavy target nuclei has been discussed. The multiplicity distribution, average multiplicities, multiplicity correlation and the angular distributions of the secondary particles emitted in 28 Si -emulsion are calculated according to the Modified Fritiof Model and compared with the experimental data and with other available data for p, 12 C , 24 Mg at the same energy. It has been found that the modified Fritiof model can describe the multiplicity characteristics of the different emitted particles in the above-mentioned interaction with different target groups. The comparison of the experimental data with the modified Fritiof model shows no clear preference for the case of the light target while it seems to be nearer to the experimental data in the case of the heavy target and the emulsion
