Abstract
Exclusive p̄p pionic annihilation reactions in the momentum range of 403 to 670 MeV/c were analysed in terms of intermediate states involving resonances. The fractions of the various intermediate states showed no significant dependence on the incident momentum. They were compared with a statistical model incorporating SU(3) symmetry. The agreement between the model and data was moderate and qualitative. The exclusive as well as topological cross sections were compared with the same statistical model and a potential model incorporating quark rearrangement. The agreement with the latter model was better than with the first in general, but it was still mostly qualitative.
