Exclusive measurements of light charged products (LCP) in the [sup 132]Xe+[sup 197]Au collisions at 44 MeV/nucleon have been performed using MEDEA 4[pi] detection system. The admixture of each partricle type into the LCP multiplicity is found to be almost independent of the impact parameter. The data are analyzed with a formalism where the fluctuations of the multiparticle decay are described by uncorrelated Poissonian statistical distributions. The impact parameter filtering is performed using the LCP multiplicity. Self-correlation and impact parameter averagining effects are identified. The dominance of the statistical contribution in the fluctuations of the LCP multiplicity is deduced.
