Characterization of Kα spectral profiles for vanadium, component redetermination for scandium, titanium, chromium, and manganese, and development of satellite structure for Z=21 to Z=25

Abstract

In most high-accuracy x-ray experiments, characteristic radiation is used to determine calibration energies or wavelengths. This paper presents experimental results for vanadium Kα, and component refitting for scandium, titanium, chromium, and manganese, addressing a critical limitation on the current use of this approach. The influence of spectrometer broadening upon the registration of these calibration profiles is quantitatively discussed and determined. The analysis permits such calibration with insignificant loss of accuracy compared to the reference uncertainty, down to a one part per million level. In the process we reveal key empirical structural trends in Kα spectral profiles from Z..
