Book Description
Stacks of 600-micron Ilford G.5 stripped emulsions have been exposed to the internal beam of the Bevatron at three energies: 3.2, 4.8, and 5.7 Bev. Shower-particle production has been investigated at these energies. (A shower particle is defined as one whose grain density is less than 1.4 times minimum.) At each energy 114 events which had beam protons for primaries were found by area scanning. The average shower particle multiplicities per event were found to be 0.94 ℗± 0.09, 1.30 ℗± 0.11, and 1.62 ℗± 0.11. These results are compared with similar observations by cosmic-ray workers. The various theories of meson production are reviewed and Fermi's calculations for Cosmotron energies have been extended to the energies of this experiment. Production differences in heavy and light nuclei are discussed and compared.
