Abstract

This review surveys the recent developments carried out by us on positron–molecule scattering at low and intermediate energies. The relative merits between the laboratory frame rotational close-coupling (rotational LFCC) and the adiabatic nuclei rotation models near the electronic and rotational excitation threshold energies are discussed. The importance of the use of the rotational LFCC model for polar molecules is also reviewed. The rovibrational LFCC and the adiabatic nuclei rovibration models are used to calculate the scattering cross sections for e+–H2 scattering. The results demonstrate the necessity of the inclusion of the vibrational motion dynamically in the theory.
