基　　金：This work was supported by the National Natural Science Foundation of China (Grant Nos. 10374115, 10374116 and 10376160); the National High-Tech ICF Program of China, and the National Key Laboratory of High Temperature and High Density Plasma. 摘　　要：The characteristics of hot electrons produced by p-polarized femtosecond laser-solid interactions are studied. The experimental results show that the outgoing electrons are mainly emitted in three directions: along the target surface, the normal direction and the laser backward direction. The electrons flowing along the target surface are due to the confinement of the electrostatic field and the surface magnetic field, while the electrons in the normal direction due to the resonant absorption. 关键词：HOT electrons,surface MAGNETIC field,femtosecond laser PULSES
