title: Effects of the external magnetic field and chemical combination on Kbeta/Kalpha X-ray intensity ratios of some nickel and cobalt compounds.
abstract: A systematic study of X-ray intensity ratios of the K-series lines was made on compounds of nickel and cobalt to examine the influence of chemical state and 0.6 and 1.2 T external magnetic fields on energy-dispersive X-ray fluorescence analysis. The samples were excited by 22.69 keV X-rays emitted from a Cd-109 radioisotope source and characteristic K X-rays emitted from the samples were counted by means of an Si(Li) detector. For B=0, the present experimental results were compared with the experimental and theoretical data in literature. The results demonstrate a clear dependence of the Kbeta/Kalpha intensity ratios on the chemical state of the element in the sample and values of external magnetic field.
