PV II: Plenary Talk

Momentum imaging (COLTRIMS) of light molecules using short laser pulses — •Charles Lewis Cocke

The timing of heavy particle motion in small molecules can be followed in the time domain on a femtosecond scale by using momentum imaging (COLTRIMS) techniques. This talk will review the use of momentum imaging in conjunction with 8-25 fs pulses to probe the coupled electronic/heavy particle motion in non-stationary states of H2 and D2 and other light molecules. The kinetic energy release in the double ionization channel is used to clock coupled electronic/vibrational motion, using three different clocks/mechanisms for the removal of the two electrons. The talk will review the extension of this to other light molecules and the use of momentum imaging to map the structure of the outermost orbital of these. Finally, a progress report on some experiments using time-resolved Coulomb imaging in a pump-probe geometry to study chemical rearrangements will be presented.
