Polarisation components violating reflection symmetry in electron scattering from optically active molecules

In electron scattering from optically active molecules, polarisation components parallel to the scattering plane are produced by intramolecular multiple scattering in conjunction with spin-orbit interaction. Accordingly, the statement by Farago (1980) that in-plane components which may be produced by other mechanisms 'are clearly distinguishable from those due to spin-orbit interactions' cannot be sustained.
