Adiabatic surfaces are defined within the Born–Oppenheimer approximation by the energy of a given solution to the electronic Schrodinger equation at each geometry.

绝热势能面是在波恩-奥本海默近似的框架内定义的，指的是在每个几何构型下，电子薛定谔方程的本征值，即能量。

Through comparing the Ar (e,3e) double ionization experimental results at low collision energy with the theoretical calculation based on the first Born approximation which include the first order mechanisms SO and TS1, the symmetry breaking about the direction of the momentum transfer shows that the non-first order effects (such as two-step 2 mechanism) play an important role.

通过比较Ar在低碰撞能量下的(e ，3e)双电离实验结果和基于包含一次作用机制SO和TS1的一阶波恩近似的理论计算结果，表明在动量转移方向上对称性的破坏显示非一次效应(例如二型两步作用机制)起非常重要的作用。

In this paper, the theoretical model of CQI is described in an atom-diatom system in the condition of the molecular beam, based on the first-Born approximation of time dependent perturbation theory, taking into accounts the anisotropic Lennard-Jones interaction potentials. The method of observing and measuring correctly the differential interference angle is presented. The relation between differential and parameter, velocity is obtained. The relation of the integral interference angle and temperature is discussed.
