Abstract
We study numerically stabilization against ionization of a fully correlated two-electron model atom in an intense laser pulse. Our results reveal that correlation reduces stabilization when compared to results from single act ive electron calculations. However, despite this destabilizing effect of el ectron correlation we still observe a decreasing ionization probability wit hin a certain intensity domain for sufficiently high frequencies. We compar e our results from the fully correlated simulations with those from simpler , approximate models. This is useful for future work on "real" more-than-on e electron atoms, not yet accessible to numerical ab initio methods.
