High energy electron beam ionize materials, and then electron was ejected in medium. Excess electron dynamics in matter especially in n-dodecane was studied with biphenyl as a probe molecule by the femtosecond pulse radiolysis. In addition to the diffusion-limited biphenyl radical anion generation calculated from the reported mobility, ultrafast generation was observed about ten times faster than that. It is considered that there are two types of electron transport mechanism which was influenced by molecular shape and condensation.
