Results are presented of measurements of differential and integral electron excitation cross sections for the O2a1Delta sub g - X3Sigma sub g(-) transition at 0.97 eV as a function of incident electron energy from 2.6 to 28.6 eV. Differential cross sections (DCS) for the a1Delta sub g state were measured relative to elastic scattering as a function of scattering angle at each incident energy for the angular range 20-134 deg. The relative DCS values were converted to absolute values using the elastic scattering cross-section values of Trajmar et al (1971) up to 90 deg and revised values at higher angles. The DCS results, which show the typical weak dependence of an optically forbidden transition on the scattering angle, are in satisfactory agreement with previous measurements. The DCS were integrated to give integral cross sections at each incident energy. The results are in excellent agreement with previous measurements and help to establish the a1Delta sub g - X3Sigma sub g(-) transition cross section as a valuable secondary standard for the measurement of electron excitation cross sections in an unstable species such as atomic oxygen.
