Energy systematics of the K alpha L-i satellite transitions

The presence of X-ray satellites is common in X-ray spectra. The last compi lation of satellite lines, frequently cited in the open literature, is the X-ray energy collection of Cauchois and Senemaud, Wavelengths of X-ray Emis sion Lines and Absorption Edges, Pergamon, Oxford, 1978 [1], which is restr icted to electron and photon excitations. In the last decades, many ion-ind uced 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 analytic al work and in basic atomic physics research one needs the best data availa ble on the satellite lines. We are working on a new and comprehensive compi lation of experimental values for the K-satellite, and K-hypersatellite ene rgy shifts. Some problems encountered during this work are discussed. A new semi-empirical formula for the description of the K alpha L' satellite ene rgy shifts is given. (C) 1999 Elsevier Science B.V. All rights reserved.
