电子-分子散射的绝热核理论扩展到考虑电子激发的目标。波函数和散射振幅的近似表达式是从形式上精确展开的固定核，电子散射的解决方案。形式主义对待分子束缚态和连续态是平等的。我们还提出了一个修改后的表达式绝热散射振幅，预计有一个增加的范围内的有效性附近的激发阈值。（AIP）
The adiabatic-nuclei theory of electron-molecule scattering is extended to account for electronic excitation of the target. The approximate expressions for the wave function and the scattering amplitude are derived from a formally exact expansion in terms of the fixed-nuclei, electronic-scattering solutions. The formalism treats molecular-bound and continuum states on an equal footing. We also propose a modified expression for the adiabatic-scattering amplitude which is expected to have an increased range of validity near excitation thresholds. (AIP)
