Near-threshold structures in inner-shell photoabsorption processes of N2and CO

Abstract

The photoabsorption spectra near the 1s threshold of N-2 and CO are calculated by the multiscattering self-consistent-field method. Our calculated near-threshold spectra are in good agreement with the experimental data. All the excited states are treated in a unified manner in the framework of the quantum defect theory. The Z+1 model potential with the relaxed core hole is adopted in our calculation.
