The electron affinities of atomic hydrogen and deuterium have been determined by tunable-laser threshold-photodetachment spectroscopy: the electron affinities of H ({ital F}=0) and D ({ital F}=1/2) are 6082.99{plus minus}0.15 and 6086.2{plus minus}0.6 cm{sup {minus}1}, respectively. The value for H is a 20-fold improvement over previous experimental determinations.
