Program Description:
The photoionization and dissociation dynamics of atoms and molecules can be significantly influenced by electron-electron correlation and the continuum electronic structure of the system. An observable that is particularly sensitive to these effects is the photoelectron or photoion angular distribution. In this presentation, I will show how a high-brightness high harmonic generation light source and an electron-ion coincidence momentum imaging spectrometer (REMI/COLTRIMS) can be used together to drive two-photon absorption in the VUV, while performing energy- and angle-resolved measurements on the emerging photoelectrons and photoions. Several examples will be provided illustrating how these measurements can elucidate the photoionization and dissociation dynamics, and reveal the degree to which electron-electron correlation and the continuum electronic structure shape these processes.
