摘要：

Recent experimental results in antinucleon-nucleus interaction obtained by the OBELIX collaboration at LEAR are presented. Preliminary results concerning the total antineutron-nucleus annihilation cross section at low energy are reported. They represent the first complete set of measurements on medium and heavy nuclei available in the momentum region below 300 MeV/c. A new measurement of the exotic one-meson annihilation at rest pBAR d --> pi- p (Pontecorvo reaction) with the better statistics and precision up to now, is reported. Finally, the measurement of the K+K-/pi+pi- production ratio in pBAR annihilation on gaseous D2 at NTP is presented. From this ratio an upper limit of the P-wave contribution to the ppBAR annihilation in GD2 is inferred.
