Abstract

Measurements of the differential cross section for the elastic scattering of low-energy electrons by

O_{2}

at 50° exhibit structure resulting from the compound state

O_{2}^{-}

. From these observations we calculate the spectroscopic constants of the ground state

{}^{2}Π_{g}

of

O_{2}^{-}

, and we find the values

ω_{e} (O_{2}^{-}) = 1089

{cm}^{- 1}

and

r_{e} (O_{2}^{-}) = 1.377

Å. A portion of the potential-energy curve of the

O_{2}^{-} ({}^{2}Π_{g})

is plotted using the Morse-function representation and our calculated values of the spectroscopic constants.
