Abstract
I will present results from computational studies of photoionization and photodetachment of molecular systems which probe the electron dynamics. Of particular interest are shape resonances, which can dramatically affect the observables including the molecular frame photoelectron angular distributions (MFPADs) as well as the photoemission time delays. These observables are dependent on the phases of the underlying transition matrix elements and their energy dependence. In the presence of a resonance, the matrix elements can very rapidly with the photoelectron energy, emission direction, and molecular structure. Examples will be presented from recent studies on systems ranging from diatomic molecules to molecular systems ~10 atoms.

Robert Lucchese is a Senior Scientist and Lawrence Berkeley National Laboratory (LBNL). He has performed extensive research on the theory and computation of electron-molecule collision with a particular emphasis on the dynamics of photoemission. Lucchese developed codes to study such processes during his 33 years in the Department of Chemistry at Texas A&M University before moving to LBNL in 2017 to work in the Atomic Molecular and Optical Science Theory Group at the lab.
