摘　　要：本论文利用杜,赵等人的半经典轨道理论,推导了电场和金属面同时存在时,氢负离子的剥离电子通量分布,并对干涉图样进行了数值模拟.结果发现剥离电子通量分布不仅与激光光子能量和外场有关,并且敏感地依赖于金属面与氢负离子之间的距离.这些结果可以应用于许多重要的研究领域,包括超快激光表面催化,更准确的测量电子亲和力和控制低能的光电子和表面的相互作用等.Based on the semi-classical theory of Du and Zhao ,the electron flux distribution of H-in the e-lectric field near a metal surface is deduced ,and the interference pattern is simulated .It is found that the electron flux distribution is not only related to the laser photon energy and external field ,but also sensi-tively depends on the ion-surface distance .This result has potential applications in many important re-search fields including surface catalysis and generation of ultrafast lasers ,the accurate measurement for electron affinity and the control of the interaction of the very low energy photoelectrons with specific re-gions of surface .
