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.
