ABSOLUTE OPTICAL OSCILLATOR-STRENGTHS FOR THE PHOTOABSORPTION OF MOLECULAR-OXYGEN (5-30 EV) AT HIGH-RESOLUTION

Absolute optical oscillator strengths for the photoabsorption of molecular oxygen in the valence shell discrete electronic excitation region have been measured in the energy range 5-30 eV using high resolution dipole (e, e) spectroscopy. Absolute intensities for the Schumann-Runge continuum region and for the discrete bands below the first ionization potential are reported and compared with available experimental and theoretical data.
