论文摘要
此处开发的理论方法可将分离性重组(DR)的直接和间接机制均匀处理。目前的理论基于在分子中几个内部距离距离进行的电子散射计算。很容易实施,因为无需分别评估中性分子的耦合和结合的分离状态。该理论可以应用于有或没有电子共振的分子离子。该方法用于计算Electron-CH $^+$碰撞中的DR横截面。计算出的横截面通常与验证方法验证该方法的低温存储环实验中的最新状态分辨数据一般吻合。
The theoretical approach developed here treats uniformly the direct and indirect mechanisms of dissociative recombination (DR) in a diatomic ion. The present theory is based on electron scattering calculations performed at several internuclear distances in the molecule. It is easy to implement becaus there is no need to separately evaluate couplings and the bound dissociative states of the neutral molecule. The theory can be applied to molecular ions with or without electronic resonances at low energies. The approach is applied to compute the DR cross section in electron-CH$^+$ collisions. The computed cross section agrees generally well with recent state-resolved data from a cryogenic storage-ring experiment, which validates the approach.
