“…In Fig. 9 =12:46:42,fairly close to the experimental ratios [43] for the I-2M»M» decay in Ar 15:48:37. The simplicity of this interpretation is remarkable given the complexity of the first step that has been interpreted as populating a large number of strongly interacting states which seems unnecessary for an understanding of the second step.…”

“…The energy positions and intensity distribution of the lines closely resembles those in the normal Auger spectrum of the isoelectronic Ar atom. 15 The energy splitting is also in an excellent agreement with the energy separation of the Cl ϩ energy levels 16 ͑see Table I͒. Consequently, the dissociation process HCl*͑2 p 5 *͒→H͑1s ͒ϩCl*͑ 2 p 5 3 p 6 ͒ ͑1͒ must have developed so far that the molecular influence has disappeared before the Auger transitions, contributing to these peaks, occur.…”

High-resolution Auger electron spectra from the decay of the Cl 2 p→* excitation in HCl and DCl have been measured. The spectra are analyzed, separating molecular and atomic features, which are assigned to transitions to the HCl ͑52͒ 4 * and Cl (3s3 p) 6 states, respectively. Auger line shapes, as affected by the molecular dissociation, are studied by comparing the experiment with the results of Monte-Carlo computer simulations based on a semiclassical model.

“…Lagrangian multipliers were used to obtain orthogonality with bound orbitals and the j javerage exchange interaction between the Auger electron and the residual ion was fully taken into account. The details of the numerical procedure used in the MCDF code has been described recently by Tulkki et al [10,24].…”

The energies, intensities, and angular anisotropies of the Ne KL-LLL satellite Auger lines have been studied by the multiconfiguration Dirac-Fock method. In addition to the initialand finalstate correlation eHects, we have studied the inBuence of the quantum beat efFect on this Auger spectrum. Since the energy splitting of the Ne 1s 2p P multiplet is much smaller than the lifetime broadening, the coherent excitation of these initial states by the in time and space localized electromagnetic pulse of the projectile has a drastic efFect on the angular distribution of Auger electrons. To analyze this coherence eKect we have generalized the theory of the angular distribution of Auger electrons to the case of coherent excitation of partially overlapping initial states. The results of our calculations are in good overall agreement with experiment. However, for a quantitative study of the in6uence of the coherence and the initial spin state on the anisotropy of these Auger lines new measurements with lower error limits are necessary.PACS number(s): 32.80.Hd, 32.80.Fb
