Auger decay of core valence double photoionized states in atomic mercury.

Multielectron coincidence spectroscopy has been used to study the Auger decay following the core (4f)—valence (5d, 6s) double photoionization of atomic mercury. Multiconfiguration Dirac–Fock calculations have been performed to predict the transition energies and populations of the triple ionized Auger final states. A good agreement between the experiment and simulated spectra is found. [ABSTRACT FROM AUTHOR]
