“…Studies with spin-polarized incident electrons can provide even more detailed information about the collision physics [2]. Increasingly sophisticated and detailed measurements, in concert with the advent of new theoretical methods and dramatic improvements in desktop computing power in the last decade, have placed our understanding of electronic collisions with the simplest ground-state atoms such as H, He, and the light alkalis on a firm footing [3]. Our knowledge of electronic collisions involving heavy atoms with many outer-shell electrons, in which relativistic effects can be important, is much poorer.…”

“…Our knowledge of electronic collisions involving heavy atoms with many outer-shell electrons, in which relativistic effects can be important, is much poorer. Early attempts to cobble together relativistic theories of electron-heavy-atom collisions have been severely limited by computing power, and have met with only limited success [3].…”

“…Quite different asymmetries are observed for the different sublevels. The theoretical curves-an R-matrix close-coupling calculation by Bartschat (1988Bartschat ( , 1989-show that such a detailed spin-dependent process is fairly well described by this method, whereas a distorted-wave approach (Bartschat et al . 1985;Bartschat 1988)-not shown here-fails completely to describe these data.…”

More sophisticated experimental methods to study inelastic electron–atom collisions include polarisation-correlation measurements such as electron–photon (e, eγ) and electron–electron (e, 2e) coincidence studies or stepwise electron–photon (eγ, γ) correlations. Electron correlations and spin effects can be explored on the most fundamental level in such experiments. In this paper recent (e, eγ) studies with Hg and Xe, (eγ, γ) studies with Ne and (e, 2e) studies with Xe using polarised electrons and/or polarised photons are reviewed.

“…Mercury is an important constituent of various industrial plasmas where electron collisions play crucial role in many technologically important processes, as, for example, in fluorescent and high intensity discharge lamps [1,2]. Additionally, as a heavy atom, mercury is a useful target in studies of relativistic effects in electron-atom scattering (see Andersen et al [3] for a recent review).…”
