The N3 X-ray emission spectra Ta in hafnium and tantalum carbides have been investigated for the first time. Peak locations and intensities have been compared with the results of calculations of the electron band structure of HfxTa1–xC alloys with ı= 0, 0.25, 0.5, and 0.75. It has been found that the inversion of peak intensities with increasing hafnium concentration is due to a nonmonotonic variation in the density of Ta 5d states in the valence band of these compounds Доп.точки доступа: Nazarova, S.
