Double Ionization of Unsaturated Hydrocarbons Interacting with High-Power Femtosecond Laser Pulses

Abstract

The nonsequential double ionization of four unsaturated organic molecules, , , , and interacting with strong Ti: Sapphire laser pulses are reported. Despite differences in the molecular geometry, the degree of ionization suppression and the fraction of molecules that undergo non-sequential double ionization were similar for all of these molecules.
