Abstract
We probe the attosecond electron motion in [Formula: see text], at short internuclear distances, by exact numerical solution of the 3D time-dependent Schrödinger equation in the Born–Oppenheimer approximation. We simulate a pump-probe experiment to calculate the energy distributions of ionized electrons. We start the experiment with a pump pulse that creates a coherent electronic wavepacket combination of the 1sσg and 2pσu states. We let the electronic wavepacket oscillate during a time delay Δt. In the second step of the experiment, we submit the wavepacket to an intense attosecond X-ray laser pulse. We observe an asymmetry in the energy distributions of ionized electrons that allows the mapping of the attosecond electron motion in [Formula: see text].
