- Abstract
K α , β X-ray lines from photon excitation were measured in selected elements from Mg to Cu using a high-resolution double-crystal X-ray spectrometer with a proportional counter, and the K β / K α intensity ratio for each element was obtained, after correcting for self-absorption, detection efficiency, and crystal reflectance. This intensity ratio increases rapidly from Mg to Ca but, in the 3 d elements region, the increase becomes slower. This is related to the intensity of the K β line involving valence electrons. The slow increase of this ratio in the 3 d elements region is thought to be due to the correlation between 3 d and 4 s electrons. Moreover, the chemical shifts, FWHM, asymmetry indices, and K β / K α intensity ratios of the Cr compounds, due to different valences, were also investigated using the same double-crystal X-ray spectrometer. The chemical effects were clearly observed, and the K β / K α intensity ratio was found to be compound-dependent for Cr.
