Threshold Excitation of Short-Lived Atomic Inner-Shell Hole States with Synchrotron Radiation

摘要

The Xe L subscript 3-M subscript 4 M subscript 5 (superscript 1G Subscript 4) Auger spectrum, photoexcited in the vicinity of the L subscript 3 edge, has been measured as a function of photon energy. The nd spectator-electron satellite lines show resonant behavior. The diagram line exhibits the largest (> or = 1 eV) post-collision interaction shift yet observed. For comparison with the data, the first fully quantum-mechanical calculation of the post-collision interaction in deep inner-shell Auger decay is performed, based on a resonant-scattering approach that involves a complete summation over intermediate L subscript 3 one-hole states.
