“…Careful selection of the kinematics enables details of either the ionisation mechanism or of target structure to be highlighted. An illustration of the power of the (e, 2e) technique for structure determination is given in the paper by Brunger (1996;this issue p. 347). By performing experiments at high energies under so-called non-coplanar geometry, equation (1) simplifies to a form whereby the measured (e,2e) cross section gives direct information on the spectral momentum density of target electrons.…”

In a series of experiments investigating the spin-dependent aspects of electron impact induced ionisation of atoms with a spin-resolved incident electron beam we have measured spin-resolved (e,2e) cross sections for xenon. By experimentally resolving the fine structure levels of the ground state residual ion the existence of an effect analogous to the fine structure effect in excitation has been established, whereby strong and opposite polarisation effects are observed in the ionisation of a spinless closed shell target leading to a fine structure doublet.

The experiment has been performed using a high energy resolution (⌬Eϭ0.95 eV FWHM) multichannel (e,2e) electron momentum spectrosocopy spectrometer at an impact energy of 1200 eV plus the binding energy. The measured binding energy spectra are compared and consistent with PES data available in the literature and also with the predictions of Hartree-Fock, Green's function and MRSD-CI methods. A strong splitting observed in the inner valence energy spectra due to electron correlation and ion relaxation effects is confirmed by MRSD-CI calculations. The experimental momentum profiles have been compared with calculations obtained using the target Hartree-Fock method with a minimum basis set and also a very large basis set. Density functional theory calculations using B3LYP functionals as well as large basis set MRSD-CI calculations are also reported. The agreement between theory and experiment for the shape of the orbital electron momentum distributions is generally good.
