In. Shabanova et al., INVESTIGATION OF THE EFFECT OF THE ELECTRON-EXCITATION ENERGY ON THE SHAPE OF XPS VALENCE-BAND SPECTRA OF 3D METALS, Russian metallurgy. Metally, (4), 1993, pp. 170-173
The excitation energy dependence of the e(g) and t(2g) components of t
he photoionization cross sections of 3d metals has been studied ?Be cr
oss section for the e(g) electrons responsible for hybridized chemical
bonds was shown to rise with the excitation energy. X-Ray Al K-alpha
radiation is recommended for XPS studies of chemical bonding between m
etal atoms and their environment in alloys based on d metals.
