The R-Matrix Theory of Electron-Molecule Scattering
The R-matrix theory of electron scattering from diatomic molecules is extended to include the effects of nuclear excitation. The theory is derived in a very general form and used to establish the connection between the R-matrix method, the Kapur-Peierls states, the Siegert resonances and the Feshbach projection method. The power of this approach as an analytic and computational tool is demonstrated by considering the vibrational excitation of a homonuclear diatomic molecule dominated by an isolated electronic resonance state.
