Electron–ion recombination in water vapor

A Monte Carlo simulation of electron–ion recombination in the presence of water vapor has been performed. The calculations cover a range of H2O densities and are in agreement with published low density experimental results. It is found that inelastic collisions of electrons with H2O rotational and vibrational modes enhance both the two‐body (dissociative recombination) and the three‐body recombination rate coefficients.
