“…A monatomic sample is readily available for elements of noble gas family: indeed, X-ray absorption spectra in the vicinity of K-and L-edges have been studied for most elements of the group [1][2][3][4][5]. The experimental data are used as a test for successive approximations in the theoretical calculation of photoabsorption cross-section.…”

A high-temperature cell with a double wall design has been constructed for X-ray absorption spectrometry of metal vapors. The inner cell, assembled from a corundum tube and thin plates without welding or reshaping, serves as a container of the vapor sample. It is not vacuum tight: instead, the outer tube provides inert atmosphere. Several spectra of K-edge atomic absorption of Zn were obtained in the stationary working regime below the Zn boiling point. The Kedge profile shows an extremely strong resonance and, above the continuum threshold, coexcitations of the outer electrons. Ó 2002 Elsevier Science B.V.

A monatomic sample is readily available for elements of noble gas family: indeed, X-ray absorption spectra in the vicinity of K-and L-edges have been studied for most elements of the group [1][2][3][4][5]. The experimental data are used as a test for successive approximations in the theoretical calculation of photoabsorption cross-section. The details of the edge shape and tiny sharp features on the smooth monotonous decrease of the cross-section with energy -the multielectron excitations -reveal some peculiarities of the coupling schemes and configuration interaction in these atoms [6,7].Apart from noble gases, few elements can be prepared in a monatomic gas state. The volatile elements mostly form bi-or polyatomic molecules, the non-volatiles require complex high-temperature Nuclear

“…give rise to satellite peaks in x-ray emission, 39 which presumably are excluded from the fluorescence yield measured here at the Ka 1 peak energy. We conclude that by selecting a narrow band of final states, the HRXY gives information on resonance and threshold structure which complements total absorption cross section studies.…”

“…Deslattes et al 39 and Cowan 45 reported variations in Ar x-ray spectra excited below the K-ionization threshold, at the 1s AE 4p resonance, and just above threshold which demonstrate XRRS features including linear dispersion, asymmetric line shapes, and line width narrowing. Those observations are consistent with the theoretical study of Tulkki 68 showing the evolution of XRRS into Ka and Kb XFS as the incident x-ray energy is where I(nl j ) is the subshell ionization energy.…”

“…While multielectron effects have heretofore been studied primarily through photoelectron and Auger spectrometry, x-ray emission also exhibits multivacancy effects (Deslattes et al, 1983), and processes at threshold can be studied by analyzing the (Goodman et al f 1985). This is an energy regime which cannot be explored with photoelectron spectrometry because of difficulties with metal deposition at low levels.…”
