摘要：

Relative triple-differential cross sections for ionization of Xe 4d and 5p orbitals have been measured in coplanar asymmetric kinematics. The scattered-electron energy is held at 1000 eV while the ejected-electron energy is changed so as to select energy-loss values DELTAE in or out of the region characterized by the giant resonance in the 4d double-line arrow pointing right epsilonf channel. The ionization mechanism as well as the interference be-tween the direct and resonant processes have been investigated by varying the momentum transfer in a collision at each ejected-electron energy. Strong interchannel coupling between the 5p and 4d shells in the region of the giant resonance has been observed in (e,2e) experiments. Distorted-wave-Born-approximation calculations have been compared with the experimental triple-differential cross section and used to guide the discussion.
