Experimental and theoretical study of the double-core-hole hypersatellite Auger spectrum of Ne

Abstract

We present the hypersatellite Auger spectrum of neon which contains the decay transitions of the K−2, K−2V, K−2L−1, K−2L−1V, and K−1L−1V states. The Auger decays of these types of core-hole states show different line shapes and linewidths which can be distinguished due to the high experimental resolution available for the present experiments. The individual Auger transitions are assigned based on various approaches. Complementary calculations are performed to assign the K−2L−1→K−1L−3 and the K−2L−1V→K−1L−3V Auger transitions. Based on the obtained results we were able to derive the ratio for the double to single ionization yield.
