ABSTRACT

We present results from our Electron Momentum Spectroscopy studies of gas-phase and condensed matter systems. Discussion of gas-phase measurements will focus on results for neon, argon, krypton and xenon. These Noble gas targets clearly illustrate the utility of the technique in elucidating the shape of the relevant Dyson orbitals, the influence of correlations on the shapes of these orbitals and, finally, details of electron correlations in the targets respective final ion states. Discussion of condensed matter measurements will focus on results for the Group II metal oxides. These examples demonstrate the ability of the technique to fully map the dispersion and occupation of the valence electronic band structure of solid targets.
