Energy systematics of the KαLi satellite transitions

The presence of X-ray satellites is common in X-ray spectra. The last compilation of satellite lines, frequently cited in the open literature, is the X-ray energy collection of Cauchois and Senemaud, Wavelengths of X-ray Emission Lines and Absorption Edges, Pergamon, Oxford, 1978 [1], which is restricted to electron and photon excitations. In the last decades, many ion-induced satellite measurements have been performed, the range covered in Ref, [1] have been extended for similar to 40 < Z < 92, spectator vacancy number from 2 to 7, and energy-shifts from similar to 200 to 1200 eV. In analytical work and in basic atomic physics research one needs the best data available on the satellite lines. We are working on a new and comprehensive compilation of experimental values for the K-satellite, and K-hypersatellite energy shifts. Some problems encountered during this work are discussed. A new semi-empirical formula for the description of the K alpha L' satellite energy shifts is given. (C) 1999 Elsevier Science B.V. All rights reserved.
