Abstract
In this paper, the quasistatic model is extended to describe the double
ionization of helium in an intense linearly polarized field, yielding
insight into the two-electron correlation effect in the ionization
dynamics. Our numerical calculations reproduce the excessive double
ionization and the photoelectron spectra observed experimentally
both quantitatively and qualitatively. Moreover, it is shown that
the classical collisional trajectories are the main source of the
double ionization in the knee regime where the double ionization
yield is much higher than that predicted by the sequential single
active electron models, and responsible for the unusual angular distribution
of the photoelectrons.
