We report the background-free observation of atomic antihydrogen, produced by interactions of an antiproton beam with a hydrogen gas jet target in the Fermilab Antiproton Accumulator. We measure the cross section of the reaction {ovr p}p{r_arrow}{ovr H}e{sup {minus}}p for {ovr p} beam momenta between 5203 and 6232 MeV/c to be 1.12{plus_minus}0.14{plus_minus}0.09 pb. {copyright} {ital 1998} {ital The American Physical Society}
