Parametrization of Kβ′′ and Kβ2,5 X-ray contributions in Kβ spectra of 3d transition metal compounds
Large database of high resolution K β X-ray emission spectra of selected 3 d metal (Ti, V, Cr, Mn) compounds obtained after excitation by 2 and 3 MeV proton beams have been built. Analysis of (relative) positions and intensities of K β ′′ and K β 2,5 X-ray contributions as a function of chemical and...
