摘要：
We have observed an intensity dependent geminate recombination of electrons in neat water. Since the recombination dynamics occurs on a time scale comparable to the solvation dynamics, the kinetics characteristic of an isosbestic wavelength are obscured. We have hypothesized that this intensity-dependent geminate recombination is due to the existence of two mechanisms for electron production with different characteristic thermalization distances. These results clarify the discrepancy between experiments at higher intensities and those at lower intensities.
