摘要：
Recent accurate measurements of the stopping powers of eleven halogenated hydrocarbon compounds for protons and alpha particles in the respective energy intervals of 0.5-2.1 MeV and 1.6-3.0 MeV have been analyzed in the context of Bethe theory, modified by inclusion of Barkas-effect and Bloch terms. The values of various parameters of the formulation were ascertained through two- and three-parameter fits to the data. The results were generally consistent with anticipated deviations from the additivity rule.
