Coherent multiple production in proton-nucleus collisions at 200 and 300 GeV/c

Abstract
Two stacks of nuclear emulsion were exposed to 205- and 303-GeV/c proton beams. By following the beam protons, inelastic events induced by proton-nucleus collisions are obtained. Then the mean free path for coherent production and its energy dependence are studied. Finally, a feature of the target-mass-number dependence of the cross section for the inelastic proton-nucleus collision is shown.
