Description

Obtained evaluations of annihilation channel sections show that during transition from the region psub(lab) < 10 GeV/c to the region psub(lab) > 10 GeV/c observed is a more rapid decrease of averaged square of reaction matrix element with energy growth where psub(lab)- momentum of incident antiproton. Polar angle cosine distribution of pions from annihilation events is very anisotropic. Anisotropy degree increases with enhancing secondary pion pulse. The anisotropy dagree drops with multiplicity growth and for nsub(+-) >= 12 pion distribution approaches isotropic. Mean transverse momentum of pions from annihilation events exceeds psub(T) pion values from nonannihilation events. Analysis shows that this exceeding has a dynamic nature
