(1995)

We investigate experimentally the issue of selecting classes of multiple particle decay events in nucleus-nucleus collisions at intermediate energy taking into account the fluctuations of global observables. We show that observed binomial-like multiplicity distributions do not necessarily imply evidence of reducibility to an elementary binary emission probability.
