RT Journal Article T1 Positron interactions with nitrogen and oxygen molecules: elastic, inelastic and total cross sections A1 Ellis-Gibbings, Lilian A1 Blanco Ramos, Francisco A1 García, Gustavo AB Positron scattering cross sections, used for modelling particle transport in various media, are difficult to gather experimentally. As such, various cross section calculation methods have been developed to varying accuracy. The IAM-SCAR+I method has been improved upon recently to fulfil the optical theorem and the results for two important simple molecules, N-2 and O-2, are presented here. These results are compared to literature and our findings are comparable in most impact energy ranges.
