| Zusammenfassung | Differential studies on two and three-photon double ionization (DI) of atomic lithium have been performed for photon energies of 50 eV and 59 eV at I ≈ 5 × 1013 W/cm2. At 50 eV DI proceeds via the simultaneous absorption of two photons resulting in the correlated emission of two electrons. In contrast for a photon energy of 59 eV, the resonant one photon transition (1s → 2p) is followed by DI through a second photon. Additionally a competing sequential three photon reaction is observed for both energies. The experimental data is compared with results from non-perturbative close-coupling calculations. |
