Energy spectra of protons emitted in p+Xe yields p+... interactions at 2.34 GeVeV/c and π-+Xe yields p+... interactions at 9 GeV/c

The results of investigation of proton energy spectra PES emitted in the reactions p+Xe yields k.p.+... at 2.34 GeV/c (k=1-9) and π-+Xe yields k.p.+... at 9 GeV/c (k=1-17) are given. Experimental data are obtained by means of a 26-litre xenon bubble chamber. It has been found that PES are satisfactorily described by a simple phenomenological formula irrespective of their emission angle (in e.s.) The parameter called temperature is independent of the K number of protons emitted into the back hemisphere (in l.s.) beginning with the primary pion energy approximately 3 GeV. The parameter determining the slope of ESP emitted into the back hemisphere in e.s. irrespective of the multiplicity of their emission is not changed with the energy of bombarding hadrons, beginning from approximately 3 GeV. The observed fact of the existence of a uniform description of PES emitted in investigated interactions irrespective of the multiplicity and particularly their emission angle as well as the nucleus-target, the hadron type and energy causing the interaction, indicates that the exponential fall of invariant cross sections cannot be considered as a distinctive feature of a definite separate class of nuclear reactions
