K-BETA K-ALPHA INTENSITY RATIOS AND CHEMICAL EFFECTS OF SOME 3D ELEMENTS/

The K beta/K alpha intensity ratio for pure 3d elements and some of th eir chemical compounds were measured with a high-resolution Si(Li) det ector. The K vacancies were produced by radiation from an x-ray tube. Metallic foils and thick pressed discs containing polyvinyl alcohol as an organic binder were used as targets. The K beta/K alpha intensity ratio was estimated from the spectrum by an evolutionary fit algorithm and corrected for detector efficiency, self-attenuation in thick samp les and background radiation. The results are compared with other expe rimental and theoretical values. They indicate a general increase in t he K beta/K alpha intensity ratio with increasing oxidation number.
