A fine structure of K beta x-ray line in titanium and vanadium compounds

The effects of chemical environment on x-ray spectra are often demonstrated for the K series lines of transition metals. In this work we present high resolution studies of Kß line profiles for pure element and compounds of vanadium and titanium. Measurements were performed using simple experimental setup that consists of the scattering chamber with thin kapton x-ray exit foil and of the high resolution spectrometer positioned at the 90 degree angle in respect to the beam direction. X ray spectrometer is enclosed in helium atmosphere and consists of a LiF(110) flat analyzing crystal and a position sensitive proportional counter (PSPC) [1]. Second order radiative contributions in the measured Kb1, 3 X-ray spectra were clearly resolved, including Kb’ , Kb” , Kb5 X-ray lines and KbL1 satellite line. Intensities and positions of these lines relative to the Kb1, 3 line were extracted. These have been correlated with oxidation states of titanium and vanadium. The influence of proton beam energy has been investigated as well. From the comparison of spectral profiles and analysed relative X-ray intensities data, it is demonstrated that titanium and vanadium chemical compounds may be suitably classified by their corresponding K X-ray spectra obtained in this way.
