ResumoWe study the the fluctuations in the number of intermediate mass fragments produced in heavy ion collisions. Of particular recent interest are the questions of scaling and reducibility of the probability distribution function of this observable. We show that the observed reducibility is a spurious effect, due to finite-number effects and the correlation between the measured transverse energy and the total charge recovered in the detector, Using only very simple assumptions, we are able to reproduce the observed binomial emission probabilities and their dependencies on the transverse energy, Finally, using the percolation model, we also show that useful information on the mechanism of intermediate mass fragment emission can be extracted from completely reconstructed events.
