摘要:
AbstractIt is shown that when a narrow x‐ray beam is used in energy dispersive fluorescence analysis of thick, low‐Z samples large deviations from the predictions of the commonly used fundamental parameter model occur. A simple method by which the effects can be studied empirically is described. An approximate model allowing a direct calculation of the effécts is introduced. The validity of the model has been confirmed experiment
