Abstract

The first part of this paper deals with instrumentation, and the second with interpretation of emission bands. The reflection and diffraction of X-rays from a blazed replica grating and the use of a flow proportional counter in the soft X-ray region are discussed. Carbon contamination by electron bombardment is shown to be largely due to CO and means for reducing carbon contamination are given. Some of the interstitial compounds of Groups IV, V, and VI of the first and second series have been studied, and the emission bands from both metal and nonmetal measured. Changes in intensity and wavelength with chemical combination are related to changes in electron distribution. For nonstoichiometric compounds such as TiO x and TiC x there was a change in wavelength with a change in x, which is also related to changes in electron distribution. A comparison of shape of emission bands with crystal structure indicates that, in general, NaCl-type structures have symmetrical bands with narrow bandwidths compared to hexagonal structures, which have asymmetrical bands.
