High-resolution angle-resolved electron spectroscopy with synchrotron radiation has been used to study the angular distributions of resonant-Auger processes near the core-level thresholds Ar2p, Kr3d and Xe4d. Angular-distribution parameters (β) were measured for all resolved peak in the electron spectra and large negative values of β were found for some peaks. A quantitative method for calculating the angular-distribution parameters is described and results of calculations for the Ar2p3 2→4s resonant-Auger spectrum are compared with the experimental results. © 1990.
