By using the method of multiconfiguration self-consistent field, the electronic wave functions for the X /sup 3/..sigma../sup -//sub g/ and B /sup 3/..sigma../sup -//sub u/ states of O/sub 2/ are determined for twelve values of internuclear distances. From the appropriate electronic-vibrational functions, the oscillator strengths for the X /sup 3/..sigma../sup -//sub g/ ..-->.. B /sup 3/..sigma../sup -//sub u/ absorption (Schumann-Runge) continuum are calculated over the energy range of 7--9.5 eV. The results are in good agreement with experiments except at the high-energy edge (above 9 eV) which corresponds to the very steeply varying part of the potential curve. A calculation of the electron-impact excitation cross sections for the B /sup 3/..sigma../sup -//sub u/ state with the Born-Ochkur approximation is also reported for incident electron energy up to 1000 eV.
