X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays. The K and L shell x-ray fluorescence (XRF) cross sections for elements with 13 ≤ Z ≤ 92 and 35 ≤ Z ≤ 92, respectively, are calculated for an incident photon energy range keV. The XRF cross sections for Kα, Kβ, Ll, Lα, Lβ, and Lγ groups of x rays Cited by: L X-ray fluorescence cross sections of the elements with Z = 62, 64, 66, 68 and 70 have been measured at , and keV using an X-ray tube and secondary exciters of Mo, Ag Cited by: 5. The K and L shell x-ray fluorescence (XRF) cross sections for elements with 13 ≤ Z ≤ 92 and 35 ≤ Z ≤ 92, respectively, are calculated for an incident photon energy range keV.

X-ray fluorescence cross sections are calculated for the major x rays of the K series 5 less than or equal to Z less than or equal to , and the three L series 12 less than or equal to Z less than . L X-ray fluorescence cross sections of the elements with Z=62, 64, 66, 68 and 70 have been measured at , and keV using an X-ray tube and secondary exciters of Mo, Ag .

The X-ray fluorescence process. A solid or a liquid sample is irradiated with high energy X-rays from a controlled X-ray tube. When an atom in the sample is struck with an X-ray of sufficient . The sample is bombarded with X-rays. This excites the sample to generate X-ray fluorescence. The X-rays “shoot” individual electrons out of the atoms of the elements, primarily out of the . X-Ray Fluorescence spectrometry involves the measurement of emission lines observed when a material is bombarded with X-Rays. Because elements differ in the energy of the lines, and .
