Abstract: (AIP)
Nuclear track emulsions were exposed to 200 GeV protons at the National Accelerator Laboratory. One of the emulsion plates was loaded with granules of Tungsten. Interactions in the emulsion and with the Tungsten granules were located and angular measurements were made on the shower particles. The average number of charged evaporation particles produced on Tungsten was found to be 29.4 ± 4.3, which is much larger than expected. Moreover, the average multiplicity of shower particles is 16.8 ± 3.8, about twice as large as that for p‐p interactions. The corresponding values for the emulsion are 7.2 ± 0.5 and 13.9 ± 0.6 for the multiplicity of evaporation and shower particles, respectively. The angular distribution of shower particles produced on Tungsten was compared to that for p‐p interactions. These data are in qualitative agreement with recent calculations by Fishbane and Trefil.- Emulsions
