Abstract
The flexibility of the (e,2 e) technique or electron momentum spectroscopy in obtaining information on the electronic structure of atoms, molecules, and solids is demonstrated. High resolution electron momentum spectroscopy measurements for argon including the first measurements of momentum profiles belonging to the {sup 2} p{sup 0} and {sup 2}D{sup e} manifolds are used to demonstrate the technique for atomic targets. The d-wave transitions in argon are entirely due to initial state correlations. The first (e,2 e) measurements on an excited target and also on an oriented target are also discussed. Sodium atoms are pumped to the m{sub l} = +1 state of the excited 3 p state by {sigma}{sup +} light from a laser. The (e,2 e) measurements on this excited state are in excellent agreement with the momentum density given by the 3 p (m{sub l} - 1) Hartree-Fock wavefunction. The recent measurements of the valence electron momentum distributions for ethane as well as some earlier results for water are used as an example of the application of EMS to the study of molecules. The application of the EMS technique to measure spectral momentum densities in condensed matter targets is demonstrated by some recent results on amorphous carbon.
