Investigations of the processes of excitation and ionization of multicharged ions by electron collisions are reviewed. It is shown that the Coulomb--Born method with exchange, for calculating cross sections of these processes, is identified here with the perturbation theory in a small parameter--the reciprocal of the ion charge. Resonant scattering substantially alters excitation cross section in a small region of collision energies; however, its contribution to excitation constant is small. Relativistic effects are also considered.
