The antiproton-helium reaction cross section has been measured at 19.6 and 48.7 MeV with a streamer chamber in a magnetic field. Charged prongs and negative pion multiplicities and cross sections for the production of He-3 are given. A comparison with pbar H-2 is performed. The previously obtained 179.6 MeV results are also taken into account.

Abstract
The antiproton-helium reaction cross section has been measured at 19.6 and 48.7 MeV with a streamer chamber in a magnetic field. Charged prongs and negative pion multiplicities and cross sections for the production of He-3 are given. A comparison with pbar H-2 is performed. The previously obtained 179.6 MeV results are also taken into account.
