Résumé

What happens when an electron scatters with a binding potential close to which there is another electronic system? One possibility is ICEC (inter-Coulombic electron capture): the binding potential takes up the electron, the neighboring system is being ionized. In numerous systematic electron dynamics calculations with antisymmetrized MCTDH (Heidelberg implementation) we have obtained a roadmap of the geometric conditions for successful ICEC. Our interpretations can straightforwardly be applied to quantum dot systems. In expanding applications at trapped ions are at hand. The other process investigated is ICD (inter-Coulombic decay). It requires a resonance state spread over two binding potentials that decays into a singly-ionized continuum state. The quest of the last years was to enhance the dimensionality of the problem. One big step towards a more-than-1d-continuum has been made in making the Coulomb interaction potential significantly more handy via multigrid POTFIT. The other was including a third electron in MCTDH.
