Electronic Collision Cross Sections and Oscillator Strengths for Oxygen in the Schumann—Runge Region

Abstract

Electron collision cross sections have been determined for that transition in oxygen corresponding to the dissociation continuum of the Schumann—Runge bands. Generalized oscillator strengths have been calculated from the data and extrapolated to zero momentum change for the colliding electron. The extrapolated value obtained, when integrated over the transition, is 0.230. This value is compared with oscillator strengths obtained from ultraviolet absorption spectra by other investigators.
