Abstract
For the first time, a full-dimensional quantum-mechanical description of excitation, dissociation and ionization of H2+ in intense laser fields is presented. The quantum-mechanical propagation of the nuclei is carried out approximately using time-dependent Floquet surfaces and the Coulomb surface, switching between these surfaces is possible stochastically (”hopping”). The impact of quantum effects in the nuclear dynamics on dissociation and ionization as well as their interplay is investigated in detail. The results are in excellent agreement with experimental data. It is shown in particular that quantum effects in the nuclear dynamics are essential for the description and interpretation of the experiments.
