12 Oct 2000 | | Journal: | Phys. Rev. A 63, 043414 (2001). | | Subject: | Atomic Physics; Chaotic Dynamics | physics.atom-ph nlin.CD quant-ph | | Abstract: | We discuss the final stages of double ionization of atoms in a strong linearly polarized laser field within a classical model. We propose that all trajectories leading to non-sequential double ionization pass close to a saddle in phase space which we identify and characterize. The saddle lies in a two degree of freedom subspace of symmetrically escaping electrons. The distribution of longitudinal momenta of ions as calculated within the subspace shows the double hump structure observed in experiments. Including a symmetric bending mode of the electrons allows us to reproduce the transverse ion momenta. We discuss also a path to sequential ionization and show that it does not lead to the observed momentum distributions. | | Source: | arXiv, physics/0010031 | | Services: | Forum | Review | PDF | Favorites | |
