Decay of the Na1s−1 state — •Andrei Kochur1, Birgit Kanngießer2, Kai Godehusen2, and Peter Zimmermann2 — 1Rostov State University of Transport Communication, 344038 Rostov-na-Donu, Russia — 2Institut für Atomare und Analytische Physik, Technische Universität Berlin, Hardenbergstr. 36, 10623 Berlin
Yields of the Naq+ ions produced by the decay of the Na1s−1 states are measured using photoelectron-photoion coincidence technique and calculated using the branching ratios obtained in configuration-average Hartree-Fock approximation. Measured yields of the photoions with q = +1, +2, +3, +4 are 0.0139, 0.636, 0.331, 0.019. These compare well with the calculated values: 0.023, 0.645, 0.332, 0.000. The experiment could only be reproduced if the mixing of the KLL decay channels 2s−2 and 2p−2 is considered. The remaining discrepancy is due to the double Auger processes which has not yet been included in the calculation.
