Experimental data on inclusive spectra of protons in interaction of 3.6-GeV/nucleon α particles with Cu and Sn nuclei

Results are reported on the study of inclusive spectra of protons emitted in interaction of 3.6-GeV/nucleon α particles with Cu and Sn nuclei. Proton angular distributions are given for three intervals of velocities: 0.325< or approx. =β< or approx. =0.425, 0.425< or approx. =β< or approx. =0.525, and 0.525< or approx. =β< or approx. =0.625. The nature of the angular distributions is practically independent of the combination of colliding nuclei but is substantially different for different velocity intervals. Total cross sections and average charged-particle multiplicities are found in the velocity interval β> or approx. =0.32. Rapidity distributions are obtained for the invariant cross sections for proton production in the rapidity range -0.2< or approx. =Y< or approx. =0.6 for 0.35< or approx. =p/sub perpendicular//mc< or approx. =0.7
