Abstract
Proton multiplicity fluctuations in nucleus-nucleus interactions at a momentum of 4.2 GeV/c per nucleon are investigated using the method of factorial moments. In collisions of light nuclei, the moment is a non monotonic function of the azimuthal angle deltaphi. This dependence ca nnot be obtained within the framework of the cascade-evaporation model . Any dynamical effects disappear in interactions of C and Ta nuclei, and fluctuations turn out to be of purely statistical nature.
