Excess electrons in neat polar liquids and microheterogeneous pseudophase systems is a topic of current interest. Recent work has shown that not all the electrons generated by photoionisation, in certain nonionic micellar pseudophase, escape into bulk water but a small fraction gets solvated in the palisade region. Electron pulse irradiation of surfactant-water mixtures generate excess electrons concurrently in both phases, the energy deposition being a function of the electron density fraction of each component.
