HYDROGEN AND HYDROGEN PEROXIDE YIELDS IN THE RADIOLYSIS OF WATER: A COMPARISON OF STOCHASTIC AND DETERMINISTIC KINETIC MODELS.

Stochastic techniques for the modeling of microscopic clusters are applied to a H/OH system, similar to that arising from the radiolysis of acid solution, and the time-dependence and the final product yields are compared with those calculated using deterministic models. The latter are shown to seriously overestimate the molecular yields, H//2 and H//2O//2, by comparison with full Monte Carlo simulation, whilst the stochastic Independent Reaction Times and Master Equation models give much better agreement.
