A method for inverting energy-loss measurements into time and space, permitting explicit imaging of electron dynamics in a medium was demonstrated. It allowed the determination of spatial extent of an excitation, i.e., its quantum dephasing distance and a parallel with pump-probe techniques to be drawn. The structure of the electron cloud around a photoexcited chromophore in solution was also determined. The results show that energy-loss scattering can be applied to the study of attosecond phenomena.
