Abstract

Experimental evidence of double photoionizations at core levels of S (Z = 16) and Ar (Z = 18) is presented. Measurements of K alpha line intensities were carried out in the region of the double-photoionization Kedge energy using monochromatic synchrotron radiation. From these measurements, double K-ionization energies were obtained and double-photoionization K-edge jumps were calculated for these elements. A discussion on the effects of double Kvacancies on XRF analysis is presented, and some approaches to the treatment of multiple vacancies in XRF are pointed out.
