Abstract:


Anomalous photo-electron angular distributions are observed at certain wavelengths in strongfield ionization of H2. We relate this feature to ac-Stark shifts from bound-bound transitions in the Rydberg manifold of principal quantum number n=3 and 4. A model of the multi-state interaction supports this interpretation.
