Analytic expressions of the direct, resonant and interference contributions to the differential cross section of a resonant Auger process, produced by the photoionization of a linear molecule either "fixed-in-space" or belonging to a gas of randomly oriented molecules, have been derived following Dill's procedures but going beyond the two-step approximation. Angle-resolved Auger spectra of the C2H2 molecule measured on top of the C1s->pi* resonance have been calculated and compared with experiments, analysing also the different contributions to the electron angular distributions.

Abstract

Analytic expressions of the direct, resonant and interference contributions to the differential cross section of a resonant Auger process, produced by the photoionization of a linear molecule either "fixed-in-space" or belonging to a gas of randomly oriented molecules, have been derived following Dill's procedures but going beyond the two-step approximation. Angle-resolved Auger spectra of the C2H2 molecule measured on top of the C1s->pi* resonance have been calculated and compared with experiments, analysing also the different contributions to the electron angular distributions.
