Energy and Momentum Spectra of Nucleons Emmited in High Energy Hadron-Nucleus Collisions

摘要

Energy and momentum spectra of ''fast'' protons, of kinetic energy from about 20 to about 400 MeV, are studied in pion-xenon nucleus collisions at 3.5 GeV/c momentum, in two classes of events - when particles are produced and when particle production does not occur. The spectra are practically the same in both the classes of events and in corresponding subclasses of events - with various multiplicities of emitted protons. Results obtained allow one to conclude that: 1) The fast nucleon emission process proceeds independently of the particle production process; 2) The knocking-out. mechanism of the fast nucleon emission does not play an important role in observed emission of protons; 3) Particle production proceeds via some intermediate objects created at first inside target nucleus and decaying after having left it.
