The Single Electron Model in Photoionization
The single electron model serves three purposes: (a) it provides a “zeroth order” approximation for the direct calculation of cross sections for photoionization and for other atomic processes, (b) it provides physical insight into the mechanisms that control these processes and (c) it forms the basis for the development of theoretical methods dealing with many electron correlations. All of the above aspects will be treated in the following discussion, but first the appropriate formulas for photoionization will be developed in order to show the relationship between the model and many electron treatments.
