Abstract

The cross sections for the two-step process, represented by the electron-impact vibro-electronic excitation \(X^1\varSigma ^+(v) \rightarrow A^1\varSigma ^+(v'')\) of the LiH molecule, followed by radiative decay back on the vibrational manifold of the ground state, \(A^1\varSigma ^+(v'')\rightarrow X^1\varSigma ^+(v')\), are calculated as a function of the incident electron energy from the threshold to 1000 eV. The final cross sections for the two-step process, which results in an overall vibrational excitation of the molecule, known also as E-v process, are provided for all the possible \(v,v'\) transitions among the vibrational levels, including the continuum, of the electronic ground state.

两步辐射衰减过程的横截面$$ X（v）\ rightarrow A（v ^ {\ prime \ prime}} \ rightarrow X（v ^ \ prime）$$ X（v）→A（v''） →e -LiH碰撞中的X（v'）

摘要

两步过程的横截面由电子冲击振动电子激发\（X ^ 1 \ varSigma ^ +（v）\ rightarrow A ^ 1 \ varSigma ^ +（v''）\表示LiH的分子，随后在基态的振动歧管辐射衰变背面，\（A ^ 1 \ varSigma ^ +（v ''）\ RIGHTARROW X ^ 1 \ varSigma ^ +（v'）\） ，被计算为从阈值到1000 eV的入射电子能量的函数。为两步过程的最终横截面提供了分子的整体振动激发（也称为Ev过程），用于所有振动水平之间可能的\（v，v'\）跃迁，包括跃迁。电子基态的连续体。
