Comparison between two Monte Carlo codes on determination of transient chemical yields

摘要

Monte Carlo computer codes have been independently developed at several laboratories for performing calculations of radiolysis of water. The different codes involve a wide variety of models and related assumptions in treating the many physical and chemical processes that occur. Because few detailed aspects of such computations can be directly checked by experiment, it is important to make comparisons of various predicted microscopic distributions. This paper compares results obtained with codes developed at Lawrence Berkeley Laboratory and at Oak Ridge National Laboratory. Both codes were used to calculate the spatial distributions of various radical species in spurs along the tracks of energetic electrons. Similarities and differences in the results of this preliminary study are shown. Additional work is planned.
