Abstract:
Photodissociation and photoionization of isolated gas-phase species assess and reveal aspects of quantum mechanics at a fundamental level. Imaging techniques, especially the better-resolved velocity map imaging (VMI), play central roles in light-matter interactions while efficiently and simultaneously recovering the kinetic energies and angular distributions of ensuing products. Here, we demonstrate experiments, simulations, and modeling, for developing and applying the new approach of spatial map imaging (SMI), using a VMI apparatus with specific voltage settings. We show that SMI provides the means for spatial imaging of the interaction of the ionizing laser with molecular/atomic beams, a feature assisting in multiple laser beam alignment and recovering the dynamical parameters of particles at an inherently improved resolution, extended dynamic range, and adding of a new dimension to spectroscopy. The exploitation of rigorous tests allows realizing the feasibility of this approach and the future promise of SMI solely or in combination with VMI.

The seminar will be held in Hebrew.
