Electron-Scattering and Photoionization of H2+ and HeH 2+
We have developed an efficient numerical method for calculating the electron-scattering differential cross sections (ESDCSs) and the photoionization differential cross sections (PIDCSs) of one-electron diatomic molecules based on the R-matrix propagation method in the prolate spheroidal coordinates. Analysis based on the Coulomb corrected independent atom model identifies a local minimum in the ESDCSs of HeH2 + that stems from the two-center interference, while attributing others to multiple-scattering.
