In previous experiments (project NAL#116 and 233) we have studied the interactions of 200, 300 and 400 GeV protons in nuclear emulsion. From these investigations we have published results about charged particle multiplicities and angular distributions. The publications are listed in enclosure 1. In the proposed experiment we extend this work to be interactions of 500 GeV protons in nuclear emulsion. The aim is to compare the parameters (N_h, n_s, n=ln tg θ\2) with those of the interactions of protons in nuclear emulsion at lower energy. The main features of this experiment will be: (1) Measure the average charged particle multiplicity. (2) Compare the yield of secondaries in proton-nucleus collisions to the kriown ones from proton-proton collisions, in particular with regard to the correlation to the nuclear fragmentation. (3) Measure the angular distribution of the shower particles. (4) Look for any subtle differences between proton-nucleus reactions at 500 GeV and reactions at lower energy. (5) In particular very high multiplicity events correlated to strong nuclear fragmentation will be investigated. (6) Study the two particle correlation.
