Abstract

We present an experimental and theoretical study of the angular correlation between resonant Auger and subsequent Coster-Kr¨onig electrons emitted in the cascade decay of Ne (1s-13p) resonance excited by linearly polarized light. The angular correlation has been measured for different relative orientations between the light polarization, the emission direction of the Coster-Kronig electron and the emission angle of the resonant Auger electron. All the experimental angular patterns are measured as a function of the resonant Auger emission angle and are compared with multiconfiguration Dirac-Fock model numerical results, which include electron correlations in each step of the cascade. The agreement between theory and experiment is different for the different considered decay channels; forvthe cases in which disagreement is larger it is argued that an extended configuration space must be taken into account to reproduce the experimental data.
