Off-shell Photoionization Cross-sections: Results of Calculations
In this chapter we present data for photoionization cross-sections beyond the energy conservation frame, or off-shell photoionization which are required for calculations of excited vacancy states. In Chaps. 5 and 6 we studied decay of not only simple HF vacancies but of more complex excited states that consist of several electrons and vacancies. The decay of these states generates new spectral lines, which are relatively intensive and noticeable in experimental spectra. Such effects were only briefly discussed in this book. But they are of interest and of some importance.
