In this manuscript we have mainly focused our study on the multiplicity distributions of projectile fragments and slowest target protons (black particles) released during the interaction of \(^{84}Kr\) with emulsion at 1 A GeV and their dependency on various target groups of the nuclear emulsion. In case of projectile fragments these distributions are described and have been replicated using a multi-source thermal model. The model makes the premise that collisions produce a large number of particle sources. Like a radioactive item, each source contributes a multiplicity distribution. The observations of the present study shows that the theoretical calculations utilising the multi-source thermal model and the experimental findings are in good agreement. In case of slowest target protons this study reveals a striking relationship between the target fragmentation processes and collision geometry with multiplicity distributions.
