abstract:
We report the study of light baryon production in two-prong annihilation reactions due to antiprotons stopping in gaseous
deuterium and detected by the OBELIX spectrometer (LEAR, CERN). A clear signal of the Delta(1232) production in two binary
reactions was found in both annihilation channels and the annihilation probabilities were evaluated. In addition, the annihilation probability for the prototype Pontecorvo reaction pbar d --> pi- p was measured with the best world
statistics: Y = 1.46+-0.08.=10^-5.
