“…For both Kr and Xe our FEI P coefficients in Tables V and VI are in good general agreement with experiment [11,13,15]. For most lines the discrepancies between separate experiments are larger than the difference between our FEI result and experiment.…”

The anisotropy of the resonant Auger decay of photon-excited Kr 3d~i'~5~5p and Xe 4d3/Q 5i$6p states has been studied by the multiconfiguration Dirac-Fock method. The calculations account for the configuration interaction both in the initial and in the 6nal states of the Auger decay. For the nonresolved nd (n+ 2)p (J = 1) resonances (n = 3 for Kr, and n = 4 for Xe) the average intensities and the anisotropies of the Auger lines were calculated by weighing each partial rate by the pertinent Dirac-Fock photoexcitation probabilities. Our results show that, in addition to the initialand Gnal-state correlation, both the relaxation and the exchange interaction have a substantial effect on the anisotropy of these Auger spectra. For most Auger lines there is good agreement between our calculated P parameters and experimental values for the Kr and Xe nd i (n+ 2)p photoexcitation resonances; there is also satisfactory agreement for the Kr 3d~i'~5p and Xe 4d~i~6p resonant Auger spectra. However, the remaining notable discrepancies between theory and experiment indicate that important correlation effects are still omitted in our calculations. Discrepancies between difFerent experimental results stress the need for further improvements on the experimental side.PACS number(s): 32.80.Hd, 32.80.Fb

“…In contrast the ISCI is likely to be fundamentally important for the anisotropy of the Auger decay of Kr 3d3/25@]/23/2 and Xe 4dz&&6pi~2 s~2 resonances. Previous calculations of these Auger spectra which were based on JK coupling model [3] and neglected the ISCI effect failed to reproduce the experimental data of Carlson et al [10,11].…”

“…11. Spectrum (b) is identified as being composed purely of autoionization decay and can be understood in the following manner: Aside from a direct photoemission contribution from the Ar 3s level, the first three peaks, at about 0 eV, Ϫ1.5 eV, and Ϫ4 eV, are due to different final-state multiplets of the 3p 4 4s 1 type, whereas those at about Ϫ6.5 eV and Ϫ8 eV (quite weak) are due to multiplets of the 3p 4 5s 1 type (Aksela et al, 1988b;Carlson et al, 1989). While CT is to be associated with a bond giving the 4s resonance width in (a), in (b) the lack of an Auger component implies that CT ӷ C , which merely reflects the minimum-energetic cost of charge transfer to create the positive ionic ''K'' configuration, and thus an absence of any Auger signal.…”

Charge-transfer dynamics studied using resonant core spectroscopies

The authors review the use of core-level resonant photoemission and resonant Auger spectroscopy to study femtosecond charge-transfer dynamics. Starting from simple models of the relevant processes, they examine the rationale for this approach and illustrate the approximations and known subtleties for the inexperienced experimentalist. Detailed analysis of case studies of increasing complexity are taken up, as well as the connection to related approaches using both valence excitation and the core-level fluorescent channel.

“…From a theoretical point of view, the stepwise model [14] can be applied to the interpretation of the resonance Auger spectra with a good degree of accuracy because in the vicinity of the resonance there is only one dominant channel for the excitation of an atom. The β Aug parameters for the resonance Auger spectra were measured for the first time for Ar in [16], for Kr in [15,16] and for Xe in [16,17]. A tentative interpretation of the experimental results was given for Ar in [18].…”

Temperature dependences of XPS spectra of orthorhombic and tetragonal YBa2Cu3O y compounds were measured. Variation of satellite peaks of Cu 2P for the superconducting compound coincided with a change of Cu valence which was deduced from the oxygen content. For the nonsuperconducting compound, no distinct change in XPS spectra was observed up to 770 K. The XPS spectra of O 1S showed three different states of oxygen atoms in the compound. Analyzing the temperature dependence of these peaks, they were attributed to the three oxygen configurations around copper: the octahedral, pyramidal and square planar.
