• Geminate ion recombination in liquid alkane was studied by using subpicosecond and picosecond pulse radiolysis. The observed decay of alkane cation radical was disagreement with the Smoluchowski eq. in the fast time-region. The reason of the disagreement was investigated by using a Monte Carlo simulation method.
