中文摘要：
实验研究了超短超强激光脉冲与薄膜靶相互作用中产生的超热电子角分布随激光入射角的变化．在靶面方向观测到一束方向性很好的高能超热电子．该高能超热电子束的电子数目随着激光入射角的增大而增大．对结果的分析表明，表面准静态磁场是导致表面电子产生的主要原因．
英文摘要：
The effect of laser incidence angle on the angular distribution of hot electrons generated in the interaction of an ultrashort intense laser pulse with the foil target are investigated. A new emission peaked in the target surface direction is observed for the first time. With the increase of the incidence angle, the ratio of the number of surface electrons to the total electron number increases, while the number of transmitted electron through the target decreases. It is believed that the surface hot electrons are caused by the confinement of the quasi-static surface magnetic field and electric field.
