The relative cross section for the gas‐phase photodetachment of electrons has been determined for in the wavelength region 1195–1695 nm (1.04–0.73 eV) and for in the wavelength region 620–1010 nm (2.00–1.23 eV). An ion cyclotron resonance spectrometer was used to generate, trap, and detect the negative ions. A 1000‐W xenon arc lamp with a grating monochromator was used as the light source, except for one series of experiments in which a tunable laser was employed. Single sharp thresholds were observed in both cross sections, with the result that the following electron affinity values have been determined: E.A. eV and E.A. eV.
