The focus of our research is the interaction of intense ultrashort laser pulses with molecular ions. The molecular ion beams, at a few keV, originating from an ion source (ECR), are crossed by the Kansas Light Source (KLS) laser beam. The resulting fragments are measured in coincidence by a 3-dimensional momentum imaging system, which allows for direct separation of the ionization and dissociation channels. These measurements provide the complete angular distribution of the molecular breakup around the laser polarization vector as well as the kinetic energy release (KER) upon dissociation with sufficient resolution to identify the vibrational states of H2 +. During this year we have modified the experimental setup and imaging technique to allow measurements of dissociation with zero kinetic energy release (KER→0). Taking advantage of the improved energy resolution and extended energy range we explored the dissociation of H2 +in intense ultrashort laser pulses.
