摘要：
Energy spectrum and angular distribution of fast electrons are measured in the interaction of linearly ( P and S) and circularly polarized femtosecond laser pulses with an aluminum target. It is interesting to note that the angular distribution of backward going electrons is unique for S and circular polarization. For S polarization, the angular distribution of fast electrons can be explained by taking account of the surface magnetic field qualitatively.
