Av. Koltsov, EQUATIONS FOR THE AVERAGED MOTION OF A RELATIVISTIC PARTICLE IN THE FIELD OF A WEAKLY INHOMOGENEOUS WAVE, Laser physics, 5(6), 1995, pp. 1202-1203
Equations are suggested for the description of the averaged motion of
a charged particle in the field of a weakly inhomogeneous wave in the
relativistic case. The conditions of the applicability of the equation
s obtained are specified.
