Abstract
Resonant scattering of electrons from molecules is discussed in the context of both a non-local complex potential and a local complex potential (boomerang model). Vibrational excitation cross sections are computed for an exactly solvable model and compared with those calculated within the boomerang approach. The range of applicability of the local complex potential approach is analysed in detail. A semi-local approximation to the cross sections is introduced which is only slightly different from the boomerang approximation, but leads to improved results.
