Abstract
The production of antihydrogen atoms (H) over bar(0)=(p) over bar e(+) has been observed by the PS210 collaboration at LEAR. The method assu mes an e(+)e(-)-pair creation via the two-photon mechanism in the anti proton-nucleus interaction. Neutral (H) over bar(0) atoms are identifi ed by a unique sequence of characteristics. The typical signature of e leven produced antihydrogen atoms is reported including possibly 2+/-1 background signals. The observed yield agrees with theoretical predic tions.
