    "abstract": "We study numerically stabilization against ionization of a fully correlated\ntwo-electron model atom in an intense laser pulse. We concentrate on two\nfrequency regimes: very high frequency, where the photon energy exceeds both,\nthe ionization potential of the outer {\\em and} the inner electron, and an\nintermediate frequency where, from a ``single active electron\u0027\u0027-point of view\nthe outer electron is expected to stabilize but the inner one is not. Our\nresults reveal that correlation reduces stabilization when compared to results\nfrom single active electron-calculations. However, despite this destabilizing\neffect of electron correlation we still observe a decreasing ionization\nprobability within a certain intensity domain in the high-frequency case. We\ncompare our results from the fully correlated simulations with those from\nsimpler, approximate models. This is useful for future work on ``real\u0027\u0027\nmore-than-one electron atoms, not yet accessible to numerical {\\em ab initio}\nmethods.",
