“…We evaluated Auger shifts to second order. The present results seem more reliable than those of earlier works by Chen, Crasemann, and co-workers [27,28]. Preliminary results on higher-order corrections seem to indicate that further improvement can be made at the level of the many-body corrections.…”

Wavelengths of xenon L-series x-ray lines were measured with high accuracy using a double Aatcrystal vacuum spectrometer. Wavelengths of the more prominent xenon I( -series lines which had been obtained previously are fully reported and corrected for recent scale changes. Energies of forbidden transitions, such as 1s-2s, have been determined from redundant combinations of Kand L-series measurements. Transition energies have been calculated relativistically including relaxation to all orders, correlation to second order, and QED effects. Agreement between experiment and theory is of the order of 0.1 eV, except for transitions involving 3s holes where it is 1 eV.PACS number(s): 31.20. Di, 31.30.Jv, 12.20.Fv

ReducedL1level width and Coster-Kronig yields by relaxation and continuum interactions in atomic zinc

1992

Calculations of the level width I' (L, ) and the f,z and f&3 Coster-Kronig yields for atomic zinc have been performed with Dirac-Fock wave functions. For I (L & ), a large deviation between theory and evaluated data exists. We include the incomplete orthogonality of the electron orbitals as well as the interchannel interaction of the decaying states. Orbital relaxation reduces the total rates in all groups of the electron-emission spectrum by about 10 -20%. Different, however, is the effect of the continuum interaction. The L &-L»X Coster-Kronig part of the spectrum is definitely reduced in its intensity, whereas the MM and MN spectra are slightly enhanced. This results in a reduction of Coster-Kronig yields, where for medium and heavy elements considerable discrepancies have been found in comparison to relativistic theory. Briefly, we discuss the consequences of our calculations for heavier elements.PACS number(s): 31. 20.Di, 32.80.Hd, 32.70.Fw

“…A possible explanation of the relatively constant 1-2 eV discrepancy is uncalculated electron correlation effects. 16 For the inner K and L levels which are involved in these transitions, ground-state and hole-state configuration interaction with nearby bound states and with radiation and radiationless continua may have to be considered. …”
