Water, its dimer and their dissociative products (OH, H2O2, HO2) play an important role in several diverse processes including atmospheric chemistry, radiation induced damage within cellular systems and atmospheric plasmas used in industry. The interaction of electrons with these species is therefore an important collision process but since OH, H2O2 and HO2 are difficult to prepare as isolated experimental targets to date, electron scattering cross sections from such species are lacking in the literature. In this paper we report the results of a semi-empirical method to estimate such cross sections, benchmarking these cross sections against our knowledge of electron scattering from the water monomer. Calculations on HO2, H2O2 and (H2O2)2 are performed with improved Additivity Rules.
