Notes:
An analysis of electron–ion recombination rate in high-mobility liquids is presented from the viewpoint of fractal diffusion (mean-free path effect), followed by a repeated encounter formulation of partially diffusion-controlled reaction of the final step. Good agreement is achieved with experiments in liquid methane, liquid argon, and liquid krypton with an encounter reaction probability of 0.567, 0.060, and 0.383, respectively. The corresponding ratio of the fractal scale parameter "d'' to the mean-free path is found to be approximately 2.0, 4.0, and 1.0, respectively. For liquid methane the experimental variation of the recombination rate with the mean-free path agrees fairly well with theoretical calculation using the same value of the reaction probability. Other theoretical models and their limitations are briefly discussed. © 1994 American Institute of Physics.
