Proton-antiproton annihilations at 1.61 BeV/c with only two mesons in the final state have been examined in the 72-in. bubble chamber. The partial cross sections measured are p̄+p-->π-+π+, 119+/-30 μb p̄+p-->K-+K+, 55+/-18 μb. The K- distribution in p̄+p-->K-+K+ is peaked strongly forward, with 7 of the 11 K- mesons produced in the forwardmost tenth of the total solid angle. The π- events show no such effect, with only 2 of the 22 π- mesons being produced in the same forward interval. Careful study of possible contamination of these events indicates that almost all of them are genuine two-meson annihilations.
