Abstract
The variation with excitation energy of the line shapes of the Cu [Formula Presented] x-ray spectrum was measured with high energy resolution near the K-shell threshold. Fits with ab initio Dirac-Fock calculated spectra allow us to estimate separately the magnitudes and energy variations of the [Formula Presented] electron shakeup and shakeoff probabilities from threshold to saturation. The Thomas model is found to account well for the intensity evolution, in contrast with shakeoff from deeper shells. A suggested, yet unexplained, strong dependence of the shakeoff intensity saturation range on the shell number is confirmed.
