Electrons, quasifree localized

The third class of mechanisms, involving either direct ionization of the liquid or electron ejection via field-emission, has been used to study the behavior of quasifree, localized, and solvated electrons. In contrast to the photoselectivity of the previous two schemes, a cascade of events occurs when high-energy electrons impart energy to a liquid. The resulting ions, excited states, and excess electrons provide a complex spectrum to unravel. However, the temporal evolution of each of the various species differs significantly and we are able to focus on the primary picosecond event, electron localization, with little interference. 

Tp is the time in the quasifree state, while denotes the time the electron is localized. As long as ppXp p, x, the second term of the r.h.s. of Equation 22 can be neglected, and the effective mobility becomes...
