中文摘要：

一个否定分子的离子的相片分开用一个二中心的模型理论上被学习。分开的电子波浪功能作为从每个中心发源的二个协调波浪的重叠被获得。分开相片的电子流动在从否定分子的离子在大距离放的一幅屏幕上被评估。屏幕上的电子流动显示强壮的干扰，山峰位置与在在否定分子的离子的二个中心之间的距离有关。我们也为 totalphotodetachment 十字节获得了一个简单分析公式。它分别地在高、低的光子精力限制为 theone 中心系统接近一个生气的节和 two times。

英文摘要：

The photodetachment of a negative molecular ion is studied theoretically using a two-center model. The detached electron wave function is obtained as a superposition of two coherent waves originating from each center. The photo-detached electron flux is evaluated on a screen placed at a large distance from the negative molecular ion. The electron flux on the screen displays strong interferences, the peak positions are related to the distance between the two centers in the negative molecular ion. We a/so obtained a simple analytical formula for the total photodetachment cross section. It approaches one and two times of the cross section for the one-center system in the high and lowphoton energy limits respectively.
