Electron Collisions with the \( He_2^ + \) Cation
This chapter illustrates one application of the R-matrix approach to electron collisions with diatomic molecules. The \( He_2^ + \) cation is the chosen target and the scattering equations are solved within a two state approximation in which those target states are represented by a complete configuration interaction (CI) expansion. Our work is one of the latest in a long line of applications of R-matrix theory to the field of electron-diatomic molecule collisions; the field began with the paper by Schneider on e − − H2, work which was soon extended to the more complex e − − F2 interaction.2 Only the details of applying R-matrix theory to the e − − \( He_2^ + \) system are presented here because the theoretical aspects of the method have already been outlined in chapter 1 and the specific computational implementation that was used in the previous chapter.
