A theory, based on the impulse approximation, of the (e,2e) process of quasielastic knockout of electrons from atoms, molecules and thin films by an incident electron with energy of about 1 keV is outlined. The (e,2e) process is an atomic-molecular analogue of the (p,2p) and (e,e'p) nuclear reactions and it enables one to obtain comprehensive information on the electronic structure of a target, namely the momentum distributions of electrons on separate orbitals of atoms, molecules and solids and their binding energies. Consideration is given to the peculiarities of the (e,2e) process on molecules (influence of molecular symmetry, hybridization of orbitals, electron correlations and the Jahn-Teller effect on the process characteristics) and in solids (investigation of plasmaron states, band structure and the surface states of electrons in crystals). The generalization of the (e,2e) method to the (..gamma..,2e) and (e,3e) processes for the purpose of direct study of electron correlations is discussed and quasielastic knockout of atoms by atoms from molecules is briefly described as a tool for investigating the vibrational wave functions and properties of radicals.
