Induced emission of electrons moving in a uniform magnetic field and an orthorhombic electric field

It is shown by a quantum-mechanical method that nonrelativistic electrons moving in a uniform magnetic field and an orthorhombic electric field are the source of induced microwave radiation.Translated from IzvestiyaVysshikh Uchebnykh Zavedeaii, Fizika, No. 6, pp. 61–63, June, 1974.In conclusion the authors thank the participants of the seminar led by A. A. Sokolov for useful discussions.
