Abstract
Branching ratios for antiproton-proton annihilations at rest into two mesons are given. The data were obtained at LEAR by stopping antiproto ns in a liquid hydrogen target. Both charged and neutral annihilation products were detected in the Crystal Barrel detector. Representative data are presented, and their bearing on the general picture of annihi lation dynamics is discussed. In addition, preliminary branching ratio s for two-body radiative annihilations are given.
