| Popis: | A general theory is developed and numerical results are presented for the angular distribution of molecular Auger electrons emitted after photoabsorption. The angular distribution reflects the dynamical properties of both processes: the photoabsorption and the Auger emission. We will analyse in detail the difference between ionization and excitation by arbitrarily polarized photons. We will show that for resonant Auger transitions the primary photoexcitation can be treated analytically. Based on this result an expression for the asymmetry parameter is developed, which determines the Auger angular distribution. Numerical results for the parameter are presented for several resonant Auger transitions of HF. |
