Invariant single-particle cross sections for pion and proton production in π ±p interactions at 8 and 16 GeV/ c are presented in terms of integrated distributions as functions of x, reduced rapidity ζ and p ⊥ 2, and also in terms of double differential cross sections E d 2 σ/(d x d p ⊥ 2) and d ζ d p ⊥ 2). A comparison of π ± and π − induced reactions is made and the energy dependence is discussed. It is shown that the single-particle structure function cannot be factorized in its dependece on transverse and longitudinal momentum. For the beam-unlike pion, there is an indication for factorizability in terms of rapidity and transverse momentum in a small central region.
