Multiplicity distribution in hadron-nucleus collisions

Charged particle multiplicity distribution in proton emulsion and pion-neon collisions have been calculated on the basis of two step production mechanisms for the secondary particles. It has been compared with the experimental results to see if the emission of secondaries from the different excited centres inside the target nucleus is correlated or uncorrelated. It is found that the experimentally observed forward-backward asymmetry in the charged secondaries in p-p collisions falls short of explaining the multiplicity distribution in hadron-nucleus collisions. Probability distribution for the number of collisions made by hadrons inside various nuclei is also given. (auth.)
