Interpretation of momentum distribution of recoil ions from laser-induced nonsequential double ionization by semiclassical rescattering model - art. no. 011404

Using a semiclassical rescattering model, the momentum distribution of reco il ions from laser-induced nonsequential double ionization is obtained and the result is consistent with the experiment reported recently. We show tha t the characteristic double-hump structure of the recoil momentum distribut ion of the He2+ ion parallel to the polarization axis is just the consequen ce of the rescattering dynamic of nonsequential double ionization and the a cceleration of the ions in the laser field.
