Abstract

Charge asymmetric dissociation into C2++O following ionization of a CO+ molecular-ion beam with intense ultrashort (7–40-fs) laser pulses is studied using a coincidence three-dimensional momentum imaging method. The data suggest that allowing the molecule enough time to stretch within a laser pulse such that it ionizes beyond the curve crossings of the C2++O and C++O+ potentials enhances the otherwise hard-to-reach charge asymmetric dissociation channel.
