Fig. 1
The electron velocity distributions for model E at four different times: at the initial state a), at ωpet = 40 b), at ωpet = 140 c), and ωpet = 200 d). Crosses correspond to f(vz), dotted and dashed lines display f(vx) and f(vy), respectively. Note that f(vx) and f(vy) overlap. The vertical line in the part a) at v/c = 0.666 denotes the monoenergetic electron beam.
