Abstract
The Glauber amplitudes for anisotropic potentials that originate from the local part of the electron–molecule interactions are examined in detail and presented in a final form which is directly suitable for numerical treatment. The various choices for the z axis are also examined and the one now most commonly employed in atomic scattering is selected. The case of rotational excitation from pure quadrupole scattering is examined for a wide variety of Q values and their effects on the form of the corresponding differential cross sections for inelastic transitions are discussed in detail.
