摘要：
We report the first experimental observation of "orientational dichroism" in electron impact-induced ionization. (e, 2e) experiments have been performed on pure angular momentum states 3P(3/2), m(F) = +3 and m(F) = -3 of the sodium atom, excited by right- and left-handed circularly polarized laser light. Our results show that the angular correlation of the final-state electron pair is strongly dependent on the mt sublevel populated. Comparison with calculation demonstrates the dependence of the dichroism on details of the scattering dynamics.
