| Abstract: | Angular distributions of spectator particles in dp and 4Hep reactions in the region of a few GeV have been studied. Significant asymmetries of the spectator particle distributions
have been observed for reactions where π-mesons are produced in the final state. Results of calculations in the framework
of a spectator model taking into account the nuclear wave function, flux factor and the energy dependence of the NN elementary
cross-sections, have been compared to experimental data. A good agreement has been observed for the fragments momenta, where
the one-pole mechanism dominates.
