Abstract
In this paper an effort has been made to study the general characteristics of slow particles produced in the interactions of 32S-Em at 200 AGeV to extract the information about the mechanism of particle production. The results have been compared with the experimental results obtained by other workers. The multiplicity distributions of the slow target associated particles (black, grey and heavy tracks) produced by 32S-beam with different targets have been studied. Also several types of correlations among them have been investigated. The variation of the produced particles with projectile mass number and target size has been studied. Also the multiplicity distributions of slow particles with NBD fits are presented and scaling multiplicity distributions of slow particles produced have been studied in order to check the validity of KNO-scaling.

Summary
The study of relativistic nucleus-nucleus (A-A) collisions has attained peculiar importance during the last few decades. It is accepted that in high energy nucleus-nucleus collisions, the emission of slow target-associated particles (i.e. black tracks) and other heavier fragments takes place at a still latter stage with range L ≤ 3 mm, relative velocity β < 0.3 and energies less than 30 MeV. These fast protons with range L ≥ 3 mm and relative velocity 0.3 ≤ β ≤ 0.7 lie in the energy range 30 to 400 MeV These target-associated particles are mostly slow and fast protons and grey particles are often assumed to be the measure of the number of encounters made by the incident hadron inside the target nucleus [3] and believed to be produced as a result of process of rescattering in the target spectator region. The multiplicity distributions of slow particles with NBD fits are presented and scaling multiplicity distributions of slow particles produced have been studied in order to check the validity of KNO-scaling
