摘 要:正In this paper, a quasistatic model is extended to describe the double ionization of Helium in intense linearly polarized field. Our numerical calculations reproduce the excessive double ionization and the photoelectron spectra observed experimentally both quantitatively and qualitatively. Moreover, the correlation between magnitude and direction of momentum in the polarization axis of two emission electrons has been studied.
