High-precision measurement of the X-ray Cu Kα spectrum.

ABSTRACT: The structure of the X-ray emission lines of the Cu Kα complex has been remeasured on a newly commissioned instrument, in a manner directly traceable to the Système Internationale definition of the meter. In this measurement, the region from 8000 eV to 8100 eV has been covered with a highly precise angular scale, and well-defined system efficiency, providing accurate wavelengths and relative intensities. This measurement updates the standard multi-Lorentzian-fit parameters from Härtwig, Hölzer, et al., and is in modest disagreement with their results for the wavelength of the Kα₁ line when compared via quadratic fitting of the peak top; the intensity ratio of Kα₁ to Kα₂ agrees within the combined error bounds. However, the
