Description of binary reactions in the relative four-velocity space

The results of analysis of binary reactions of the type of charge exchange π-+p → π0(η, ω)+n in a wide momentum interval from 3 to 200 GeV/c in the relative four-velocity space using b parameter determined by four-velocities of prticles are given. Like a hadron jet productions, the statistical regularity for binary reactions is realized - the cross sections of those monotonously and rather sharply decrease with b increasing. The B and dependence on incident particle momentum points to the universal properties of b distribution for π0, η, ω. These distributions are independent of energy beginning from pπ-=20-50 GeV/c. The parameters B and for π0 from binary reactions and for π- from the hadron jets are approximately the same
