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