“…This finding is in a good agreement with the measurement of Mehlhorn et al [9] as well as with the more recent experimental study of Kádár et al [10]. Still, the triple ionization threshold of a single neon atom is energetically too high for the autoionization of those states to be possible.…”

Recently, a computational technique for ab initio calculation of the inter-atomic and intermolecular non-radiative decay processes has been developed [1]. It combines the Fano formalism with the Green's function method known as the algebraic diagrammatic construction. The problem of normalization of continuum wave functions stemming from the use of the Gaussian basis sets is solved by using the Stieltjes imaging technique. In the present paper, the methodology is extended in order to describe the inter-atomic decay of excited doubly ionized states of clusters. The new computational scheme is applied to compute the inter-atomic decay rates of doubly ionized states formed by Auger relaxation of core vacancies in NeAr and MgNe van der Waals clusters.

“…The energies and intensities of the Ne KL-LLL Auger satellite lines have already been measured in several collision systems with different charged particle projectiles [11,18,21,[29][30][31]. In Table I our measured line energies are compared to the results of other high-resolution experiments performed with electron [11] and ion beams [18] together with the recent MCDF calculation results [9].…”

“…It was found that the difference between the calculations based on the nonrelativistic LS coupling ͑⌫ӷ͒ and the MCDF method ͑⌫ = 0.2 eV, Ϸ 0.1 eV͒ was significant. However, the uncertainties of the experimental data [11,14,18] did not allow us to arrive at a definite conclusion at that time.…”

Experimental study of coherence and correlation in the anisotropy of NeKL-LLLsatellite Auger decay

et al. 2004

The coherent excitation of overlapping atomic states by ion projectiles has a strong effect on the angular distribution of Auger electrons. Therefore, the measurement of the angular anisotropy of outgoing Auger electrons is suitable for the quantitative studies of the influence of the coherence. In our experiment the Ne target was bombarded with 700-2000 keV H + and 2000 keV He + projectiles. The angular distributions of KL 2,3 -LLL 2,3 Auger electrons emitted from the decay of the coherently excited 1s2p doubly vacancy states of Ne were measured. The anisotropy parameter of the Auger decay was deduced from the measurements and compared with theoretical results calculated using the multiconfiguration Dirac-Fock method. The results indicate that one should go beyond the LS coupling scheme even at this relatively low atomic number element, but also suggest that only partially overlapping states need to be taken into account.
