Abstract

We have observed ions with energies of up to 12.5 eV from a sample of molecular hydorgen subjected to an intense 28 ns, 308 nm laser beam. We show that these ions are strong evidence for a two-electron many-photon direct collective process, and discuss the nature of this process. The rapid dissociation occurs on a femtosecond timescale from an initial internuclear separation as short as 0.58 Å, well within the classically forbidden region.
