Abstract

The cross sections for energetic electron excitation of the parity‐forbidden

X^{1} Σ_{g}^{+} {→ E, F}^{1} Σ_{g}^{+}

transitions are calculated in the Born approximation. The intensities for these forbidden transitions are predicted to be comparable to the intensities of the allowed

X^{1} Σ_{g}^{+} {→ C}^{1} Π_{u}

and

X^{1} Σ_{g}^{+} {→ B}^{1} Σ_{u}^{+}

transitions for scattering angles as small as 0.75° for 34‐keV electrons.
