Abstract
Angular distributions of the photoelectrons and of the fluorescence are computed in the vicinity of the resonant excitation of the molecule. In the calculations, lifetime vibrational interference and the direct transition amplitude for population of the states were taken into account ab initio. The weak direct photoionization channel induces broad exciting-photon energy range dispersions of the angular distribution parameters and , and the nuclear vibrational motion causes variations of the computed parameters across the positions of the vibronic states. Present calculations are in good agreement with available vibrationally and angularly resolved resonant Auger spectra. Theoretical parameters are in agreement with the experimental results from the polarization analysis of the fluorescence induced by linearly polarized synchrotron radiation.
