Study of constant term for electron-molecule scattering: F-2, H2CO and H2O target examples
The correlation contribution to the static-exchange interaction potential (DeltaV(SE)) is an important quantity that determines the shift in resonance of electron scattering. This correlation part of DeltaV(potential)(SE), known as constant term, has been studied for H2CO, H2O and F-2 using coupled cluster singles and doubles approximation. Attractive and repulsive parts of this constant term for the target molecules have been analyzed.
