Complete disintegrations of Ag and Br nuclei caused by a 4.5A GeV/c ${}_{}{}^{28}{}_{}{}^{}\mathrm{Si}$ projectile have been analyzed to study the characteristics of the collisions with small impact parameters. The results are systematically compared with their corresponding values obtained for the interactions with comparatively larger impact parameters at the same beam momentum per nucleon. The variations of the mean multiplicity of the relativistic charged particles with the mean number of the interacting nucleons of the projectile nuclei and the normalized pseudorapidity density have also been examined.
