Angular Distribution of MolecularK-Shell Auger Electrons: Spectroscopy of Photoabsorption Anisotropy

Abstract

The angular distribution of Auger electrons emitted in the decay of molecular $K$-shell vacancies created by photoabsorption is predicted to be a direct probe of the anisotropy of molecular photoabsorption. The $\sigma \to \pi$ discrete absorption and the $\sigma \to \sigma$ $f$-wave shape resonance in ${\mathrm{N}}_2$ and CO are given as examples.
