Surface changes induced by atmospheric exposure of copper and copper-base alloys have been studied by X-ray excitation of AI K, Cu L, and Zn L X-ray spectra, using a conventional vacuum X-ray spectrograph. These are compared with spectral differences between pure metals and their oxides. The results are also related to published data obtained using electron excitation.Well defined 'chemical shifts' are observed in the AI K spectra from aluminum metal, AI203, and oxidized or tarnished aluminumcontaining alloys. Significant spectral differences are also seen between copper metal, its oxides, and tarnished copper-base alloys. As expected from elementary electron configuration data, the oxidation of zinc produces the smallest spectral change.The conclusion is that a conventional vacuum X-ray spectrograph provides sufficient resolution for the study of soft X-ray spectra in many practical applications involving surface reactions.Of the comtnen spectrographic techniques, soft X-ray spectroscopy appears the least extensively employed. Nevertheless, a recent review of the field (1) stated that: "For many years, X-ray spectroscopy has also been used to study the behaviour of electrons in solids. An analysis of X-ray emission and absorption spectra, due to transitions between a discrete inner atomic level of known characteristics and the various levels in the energy bands, usually provides the most straight-forward means of determining the distribution of the energy levels making up the band. These levels are weakly bound to the atom and describe the distribution of the occupied and unoccupied electron states in the s-olid. The physical and chemical states of an element thus modify its X-ray absorption edges and the neighbouring emission lines or bands, and information about the element's electronic orbitals in various chemical states can be obtained from X-ray spectra."

“…So far, many electronic and other physical properties of this compound have been measured. During the past four decades, the electronic structure of AuAl 2 has been studied by performing band-structure calculations [3][4][5], X-ray [6][7][8][9] and ultraviolet photoemission spectroscopic (XPS and UPS) experiments [10], angled-integrated photoemission spectroscopic (PES) work [11], X-ray absorption [10,[12][13][14] and emission [7,[15][16][17][18] studies, and optical reflectivity measurements [19,20]. The structural, electronic, magnetic, and optical properties of AuAl 2 are reviewed by Hsu [2].…”

The A1L-and K/3-emissiod bands of noble and several transition metal 293 aluminides have been investigated in (1). In the spectra of the alloys two peaks a r e observed. It was also established that the V K P -bands from the alloys V Rh, V Pd, V Ir, and V Pt a r e split into two main subbands (2). In (3) the TiKP -bands from some intermetallic Ti-Cu compounds have been investigated. It was found the valence band of these compounds consists of two subbands.This report is a continuation of the investigations (3) with the aim of studying the energy band structure of alloys of titanium with the transition metals and silver.The alloys under investigation had the following composition: Ti+90% N i , Ti2Pd, Ti Pt, TiCu, TiCu X-ray analysis. Excepting Ti Ag (4), all investigated alloys contained one phase.The fluorescent X-ray KP -emission bands of titanium were recorded photographically in the second order reflection from a bent quartz crystal ( l O i 1 ) . The films were photometered point-by-point and the results were averaged.and Ti Ag. The crystal structure of the alloys was tested byThe experimental results a r e presented in Fig. 1 and 2. The following experimenta l results should be pointed out:1. TiKP -spectra from binary titanium alloys with Cu, Ag, Pd, and Pt consist of two subbands (labelled A and B in the figure). The short-wave subband A coincides by its energetic position with the maximum of the pure titanium KP -band. Table.
