Abstract
The concept of enhancing recollisions after laser-induced ionization via antisymmetric molecular or atomic orbitals is investigated. The underlying mechanism, first motivated by classical arguments, is based on partial compensation of the electron drift induced by antisymmetry and the drift induced by the laser magnetic field. The numerical solution of the time-dependent Schrdinger equation confirms our concept in terms of the increase of the harmonic signal for the first excited antisymmetric state of H2+, as an important example of a recollision-dependent process, but also reveals novel aspects of two-centre interference structures in high-harmonic spectra. Finally, density contour plots illustrate the recollisions from antisymmetric orbitals and the virtues of employing ions rather than molecules.
