X-ray Spectroscopy and Fluorescence Analysis

General expressions are obtained which show the relation between the height and area of a photoelectron peak and the partial photoionisation cross-section. It is shown that, if the height is used as a measure of intensity, the energy spread of the incident photon beam and the analyser bandpass must be considered. The importance of having a complete knowledge of the variation of analyser efficiency with electron energy is stressed, the cylindrical mirror analyser being given as an example.
