The article presents the results of a study of characteristic X-ray spectra of free atoms by means of a new simple technique.
A pulsed electron beam was used for evaporation and to create inner-shell vacancies in free atoms of metals. The spectra were
obtained with the help of an X-ray monochromator which allowed precise comparison between the free-atoms spectra and corresponding
solid-state spectra. The shifts of the peaks were measured and found to be in the range Δλ/λ≈10−5–10−4. The K-, L- and M-series spectra were studied. A number of the free-atoms spectra revealed structure which was not resolved
in the solid-state spectra and which is of interest for atomic structure calculation applications. This electron beam technique
for the investigation of X-ray characteristic spectra of free atoms can be used for the refinement of X-ray wavelength standards. 相似文献

A new algorithm for resolving individual bands in absorption spectra is developed. It is assumed that the spectrum consists
of absorption bands with halfwidths determined by different kinds of interactions—specific and nonspecific. The method has
good accuracy in the case of the strong overlap of bands (the ratio of the distance between maxima of the peaks to the halfwidth
is less than 0.2) and a high computational efficiency.

The IR spectra and polarized Raman spectra of crystals of hexahydrates of zinc potassium and ammonium sulfates have been obtained
experimentally at 93 K and at room temperature. The frequencies and modes of normal vibrations of the octahedral complex [Zn(H2O)6]2+ have been calculated. The assignment of the observed lines of the internal and external vibrations of the crystal cell has
been made by calculations and by factor-group analysis.
