CORRECTIONS TO THE X-RAY-FLUORESCENCE EQUATIONS CONSIDERING DOUBLE K-PHOTOIONIZATION

Some of the most common multi-electron transition processes are descri bed and the effects of a double K-photoionization are analysed. Some p revious experimental results are summarized, and the fact that fundame ntal parameters (such as absorption edge jump ratios) are changed thro ugh double ionization is shown. Finally, a correction to the equations for X-ray fluorescence intensity due to the effects of the double K-i onization is proposed by the inclusion of a step-function in the emiss ion factor used in fundamental parameters calculation.
