Abstract

We present wave functions of helium atoms exposed to an intense 800-nm laser, calculated by numerical integration of the time-dependent Schrödinger equation. Around 600 TW/cm2 strong resonance enhancements of high-energy electrons occur, each leading to the appearance of specific quasi-periodic charge distribution patterns around the atom. The time-dependence of several such states is presented and discussed.
