Abstract

The electron affinity of atomic oxygen, an important calibration standard in negative-ion photoelectron spectroscopy, has been determined by tunable-laser photodetachment in a coaxial laser–ion-beam spectrometer to be 11 784.645±0.006

{cm}^{- 1}

. In addition, the spin-orbit splitting between the

{}^{2}P_{3 / 2}

and

{}^{2}P_{1 / 2}

states of

O^{-}

was found to be 177.13±0.05

{cm}^{- 1}
