Spectroscopy and Dynamics of Threshold Ionization of Clusters and Small Molecules

---

In this talk recent results on threshold photoionization and photoion-pair production will be discussed. In these experiments, coherent vacuum ultraviolet radiation is used to excite small molecules or clusters to highly excited states, which can result in the formation of conventional or ion-pair Rydberg states, which can be detected by pulsed-field ionization. This threshold spectroscopy allows us to probe the energetics, spectroscopy, and dynamics of photoionization and photoion-pair production.
