Abstract
Results are presented on the charge exchange reactionbar pp-̅nn and ̅np annihilations from bubble chamber exposures to antiproton beam of momenta 700 and 760 MeV/c. The differential cross section ofbar pp to bar nn shows a forward spike followed by a clear dip bump structure. Total annihilation cross section ofbar np for averagebar n momentum of 700 MeV/c has been evaluated to be 55.4−2.2 mb. The multiplicity, Feynman x and p2T distributions for inclusive charged pions inbar pp andbar np annihilations are found to be similar. The emission of charged pions frombar np annihilations are found to be consistent with thermodynamic models with temperature ∼110 MeV.
