Radiation of a scalar particle in the field of two oppositely directed electromagnetic travelling waves

The radiation of a charged spinless particle in a field of two linearly polarized, oppositely directed electromagnetic travelling waves is treated in the small-field approximation. Equations are derived for the radiation probability, and the polarization properties of the radiation are studied.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii Fizika, Vol. 12, No. 1, pp. 69–73, January, 1969.The authors thank Professor I.
