摘要：

The electron-impact ionization of the Fe atom is calculated in a distorted-wave approximation. A prior form of the scattering amplitude, containing a mixture of atomc and ionic potentials, produces a giant resonance in the cross section. A post form of the scattering amplitude, containing only ionic potentials, produces a cross section devoid of shape resonances. Further calculations using both forms are made for various single-, double-, and triple-differential cross sections. © 1995 The American Physical Society.
