  We analysed the binomial multiplicity moments of the neutral pions, using an
extension of the generating functional technique for detection losses. We
applied this model-independent method to the individual gamma-weights of 10000
events of pi^{-}-proton interactions at 40 GeV/c. We compared the obtained
results to those of 250 GeV/c. We used the FRITIOF and a shifted KW
distribution to describe the data.
