<i>K</i>β<sub>1,3</sub> x-ray emission spectra in the elements from Ca to Ge
ORAL
Abstract
The Kβ1,3, Kβ' and Kβ" spectra in the elements from Ca to Ge were systematically investigated using a high-resolution anti-parallel double-crystal x-ray spectrometer. Each Kβ1,3 natural linewidth was corrected using the instrumental function of this type of x-ray spetrometer and the spin doublet energies were obtained from the peak position values in 3d Kβ1,3 spectra. The width of the Kβ1 spectra linearly increases with the 3d elements. However, that of the Kb3 spectra is not linear in 3d elements and increased from Sc to Ni elements by around 0.5 eV. The contribution of Kβ' and Kβ" satellites is considered to be [KM] shake processes. From the calculation of Ca, Cu and Zn Kβ1,3 spectra, [KM] shake processes are mainly contributed to the Kβ1,3 spectra.
