Abstract.
The threshold electron impact spectrum of molecular oxygen has been studied using a high energy resolution electron spectrometer in the energy region 2-15.2 eV and the penetrating field method for scattered electrons. The measured features such as core excited resonances as well as Rydberg and valence states are measured in threshold and metastable spectra. They are identified and assigned according to their energy positions, energy spacing between vibrational levels and compared with similar data from the literature. A good agreement was found in the energy positions between measured features and corresponding potential energy diagram for Rydberg states for molecular oxygen given by Morrill et al. [1].
