Attosecond resolution quantum dynamics between electrons andH2+molecules

Abstract

The time-dependent-wave-packet method has been applied to calculate the kinetic energy distribution of ${\mathrm{H}}^{+}$ ion resulting from the recollision between the electron and its parent ion ${\mathrm{H}}_{2}^{+}({X}^{2}{\ensuremath{\sum}}_{g}^{+})$ within subfemtosecond time scale. The recollision probabilities between the electron and ${\mathrm{H}}_{2}^{+}$ as a function of time have also been obtained. Also, an accurate quantum dynamics method has been applied to describe the motion of both the electron and the nuclear wave packets with attosecond resolution. The calculated results are in good agreement with experimental ones.
