Experimental study of the pion-xenon collisions at 3.5 GeV/c momentum

Energy and momentum spectra of ''fast'' protons, of kinetic energy from about 20 to about 400 MeV, are studied. It is shown that average kinetic energy of the emitted protons weakly changes with the proton multiplicity increase. Kinetic energy spectra are almost independent of the proton multiplicity. Values of the proton longitudinal momenta lie within the -600 to +800 MeV/c range. The shape of the longitudinal proton momentum distribution depends weakly on the proton multiplicity. Proton transverse momentum values lie within the 0-850 MeV/c range. Average value of the proton transverse momentum is 300.8 MeV/c. Proton transverse momentum distributions are almost idependent of the proton multiplicity
