| 摘 要： | 研究了氢负离子在弹性墙附近的光剥离过程，导出了剥离截面的解析公式。此截面为光滑背景项与一正弦振荡项之和，后者与离子与弹性墙的距离有关。分析了光剥离电离的经典动力学及其量子对应。在本模型中，半经典光剥离截面与量子结果一致。

| Abstract: | The photodetachment of H? near an elastic wall was investigated and an analytical formula of the crosssection was derived. It was found that the cross section is a superposition of a smooth background and sinusoidal oscillation, which depends on the distance between the ion and the elastic wall. The classical dynamics of the photo-detached electron and its quantum correspondence was analyzed. In this model, the semiclassical photodetachment cross section is exactly the same as the quantum result. |
