The production of antihydrogen atoms Full-size image (<1 K) has been observed by the PS210 collaboration at LEAR. The method assumes an e+e− -pair creation via the two-photon mechanism in the antiproton-nucleus interaction. Neutral H̄0 atoms are identified by a unique sequence of characteristics. The typical signature of eleven produced antihydrogen atoms is reported including possibly 2±1 background signals. The observed yield agrees with theoretical predictions.

Abstract
The production of antihydrogen atoms Full-size image (<1 K) has been observed by the PS210 collaboration at LEAR. The method assumes an e+e− -pair creation via the two-photon mechanism in the antiproton-nucleus interaction. Neutral H̄0 atoms are identified by a unique sequence of characteristics. The typical signature of eleven produced antihydrogen atoms is reported including possibly 2±1 background signals. The observed yield agrees with theoretical predictions.
