Experimental Study of the Pion-Xenon Nucleus Collisions without Particle Production at 3.5 GeV/c Momentum: Physical Meaning of the Proton Multiplicity Distribution

摘要

Distribution of multiplicities of protons emitted in pion-xenon nucleus collisions at 3.5 GeV/c was studied in such events in which incident pion is totally absorbed within the target nucleus without produced particles. The distribution is symmetrical relatively to the proton multiplicity nsub(p)=7.4 +- 0.3. It is exactly described by binoamial formula, without any fitting, on the basis of an information about the size of the target nucleus and nucleon density distribution in it. 15 refs.
