Mass attenuation coefficients in the range 3.8 ⩽ E ⩽ 11 keV , K fluorescence yield and K β / K α relative X-ray emission rate for Ti, V, Fe, Co, Ni, Cu and Zn measured with a tunable monochromatic X-ray source

This work presents new measurements of mass attenuation coefficients in the range 3.8 ⩽ E ⩽ 11 keV , K-absorption jump-ratios, K α and K β fluorescence yields for Ti, V, Fe, Co, Ni, Cu and Zn. We use the experimental facility SOLEX, a tunable monochromatic X-ray source combined with an energy-dispersive high-purity germanium detector. The results are compared with theoretical values as well as with other experimental data and show a relatively good agreement. However, the derived K-jump-ratios appear larger than those widely used in the XCOM database. The K α and K β fluorescence yields and the corresponding relative emission rates K β / K α are also derived, which was made possible by the use of energy-dispersive detectors with good spectral resolution.
