Difference-diffraction pattern and the angular probability distribution Pr(θ, ϕ, t) at various delay times marked in e: a t = 1.9 ps, b t = 3.8 ps, c t = 4.2 ps, d t = 6.1 ps. The dark circle corresponds to the regions where scattered electrons are blocked by the beam stop. e Temporal evolution of the experimental and simulated anisotropy of the rotational wavepacket.
