ANTIPROTON-PROTON INELASTIC INTERACTIONS AT 1.61 Bev/c AND THEIR USE FOR A TEST OF CHARGE-CONJUGATION INVARIANCE IN STRONG INTERACTIONS

; ;
The reactions p-bar + p-p-bar+ pi /sup 0/, p-bar + n + pi /sup +/, and p + n-bar + protons of 1.61 Bev/c. The cross sections are measured and found to be 1.6 plus or minus 0.3 mb, 1.15 plus or minus 0.3 mb, and 0.96 plus or minus 0.22 mb, respectively. The combined inelastic (nonannihilation) cross section is estimated to be 5.3 mb, and the annihilation cross section 51 plus or minus 3 mb. The angular and energy distributions are presented. In all cases the antinucleons are peaked forward and the nucleons backward in the center-of-mass system. These events can be used to check charge- conjugation invariance in strong interactions.
