Momentum imaging spectroscopy probing strong-field molecular dynamics and surface dynamics

Wednesday, July 11, 2018 - 3:00pm

Speaker:  Lin Fan, Wayne State University

Program Description:

Electron-ion coincidence measurements in combination with 3-dimentional (3D) momentum imaging can provide comprehensive 3D-momentum information to unravel multichannel photoionization/dissociation processes, and thus is an effective tool to investigate atomic/molecular dynamics. In this talk, I will introduce a camera-based 3D coincidence momentum imaging system developed in our lab. I will present studies of strong field dissociative single and double ionization of a relatively large molecule 2-phenylethyl-N, N-dimethylamine (PENNA). I will also present a novel angular resolved-photoemission spectroscopy setup based on velocity mapping imaging (VMI) apparatus to study surface dynamics in graphene, in which unprecedented long hot carrier decay dynamics were observed.
