Outline of Final Research Achievements |
In this study, we have developed a technique of obtaining images of velocity and angular distributions of photofragment ions from cluster ions, which are important as microscopic models of nanomaterials. We have applied this technique to unveil ultraviolet photodissociation dynamics of gas-phase complex monocations of magnesium-argon and magnesium-fluoromethane. We found that both complexes exhibit fast dissociation just after electronic excitation which is localized on the magnesium monocation. In addition, we have determined a ground-state binding energy for the Mg-Ar complex from this measurement.
