Auger decay at the 1s-1np (n=3-5) resonances of Ne

The Anger electron spectra of Ne following the 1s --> 3p, 4p and 5p excitations have been measured with high resolution. For the 1s(-1)3p resonant Auger spectrum, the relative intensities of the transitions into the partially resolved 2p(4)3p final states have been extracted from the experiment. They compare favourably with the results of multiconfiguration Dirac-Fock calculations. The calculation for the 1s(-1)4p resonant Auger spectrum, even though not completely successful, also indicates agreement with the measurement. Shake probabilities have been determined from the three experimental spectra. (C) 2001 Elsevier Science B.V. All rights reserved.
