Correlations in Electron-Atom Collisions involving Polarised Electrons and Photons

摘要

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