New exact solutions of the Dirac equation. V

Four types of external electromagnetic fields allowing an exact solution of the Dirac and Klein — Gordon equations are considered. The motion of the electron in such fields is of a specific character; however, from the mathematical point of view some of the problems reduce to cases already studied in earlier papers [1–4].Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 9, pp. 106–112, September, 1975.
