The Fine Structure of K-Series X-Ray Emission Spectra of the Elements Mn (25)-Zn (30) and Ge (32)

The fine structure of the x-ray emission spectra K_α and K_β, obtained by bent crystal spectrographs, of the elements Mn (25)?Zn (30) and Ge (32) were microphoto-metrically investigated, and the wave-lengths of many weak lines have been determined. The measurement of the intensity distributions of these spectra was also carried out by the photogram-microphotometer method, and it has been confirmed that the accuracy of the results is comparable to that obtained by the double crystal spectrometer. Next, resolutions of the lines K_, K_, and K_ into their component lines were tried. In consequence, it has been shown that the structures of these lines may be considered to have some correlation with one another. The use of the net planes which give rise to reflections of large dispersion and an auxiliary lens which reduces the photographic grain effect on the microphotometric curve facilitated the perfotmance of this experiment
