We present quantum mechanical calculations of the electron and ion
momentum distributions following double ionization of a one-dimensional
helium atom by ultrashort laser pulses (780 nm) at various intensities.
The two-electron momentum distributions exhibit a clear transition
from nonsequential to sequential double ionization. We provide strong
evidence that rescattering is responsible for nonsequential ionization
by calculating the momentum spectrum of the He2+ recoil ions-which
we find in excellent agreement with recent experiments-and by analyzing
the electronic center-of-mass motion via Wigner transforms.
