摘要：
The first experimental observation of 'orientational dichroism' in electron impact-induced ionization is discussed. (e,2e) experiments on pure angular momentum states of sodium, excited by right-and left-handed circularly polarized laser light, show that the angular distributions of the final state electron pair are strongly dependent on initial state orientation of the target. Comparison with calculation demonstrates the dependence of the dichroism on details of the scattering dynamics. (C) 1998 Elsevier Science B.V.
