21. The width of the wave packet is mainly determined by the product of the duration of the pump pulse, 100 fs, and the speed of the wave packet, ∼10 Å/ps, yielding ∼1 Å. At larger delays, the dispersion of the wave packet will increase the width.
22. R due to the highly nonlinear character of the double ionization induced by the probe pulse (see Ref. 2).
