Abstract
Expressions are obtained for the spectral-angular characteristics of the radiation in two limiting cases: γξ ≪ 1 and γξ ≫ 1 (ξ is the angle of deflection of the electron in the field, and γ is the energy of the electron in units of mc2). It is shown that in the latter case the maximum of the radiation occurs at higher harmonics.
