Abstract:

This grant resulted in quantifying experimentally and theoretically photoionization from the interaction of an ultrastrong field 10exp 19 Wsq cm with atoms and small hydrocarbon molecules. The ionization charge states reached by the ionization ranged from 2 to 26 with photoelectron energies measured to exceed 1 MeV. The angular distribution of the final electron states were measured to be consistent with sequential ionization of the ions during the pulse. Correlated ionization processes would therefore have to follow closely sequential ionization, i.e. sequential and nonsequential events are estimated to occur within 5 fs of each other during the laser pulse.
