Abstract

Abstract: The x-ray atomic properties of nickel (Ni) were investigated in a unique approach combining different experimental techniques to obtain new, useful and reliable values of atomic fundamental parameters for x-ray spectrometric purposes and for comparison with theoretical predictions. We determined the mass attenuation coefficients in an energy range covering the L- and K-absorption edges, the K-shell fluorescence yield and the K β / K α and K β 1, 3 / K α 1, 2 transition probability ratios. The obtained line profiles and linewidths of the K α and K β transitions in Ni can be considered as the contribution of the satellite lines arising from the [KM] shake processes suggested by Deutsch et al (1995 Phys. Rev . A51 283) and Ito et al (2016 Phys. Rev . A94 042506). Comparison of the new data with several databases showed good agreement, but also discrepancies were found with existing tabulated values.
