Program Description
Many of the most interesting and important chemical processes, such as the transfer of charge and energy within and between molecules, occur on ultrafast time scales ranging from a few picoseconds down to less than a femtosecond. In some cases short pulses of photons or electrons can be employed to study and control ultrafast phenomena, however technical and intrinsic limitations often prohibit our access to other important tools at our disposal.
I will present some of our recent work studying ultrafast dynamics in anions by dissociative electron attachment. We focus on fundamental and model systems that have technological relevance with respect to electron-driven chemistry and radiation damage in biological systems by low-energy secondary electrons. I will also discuss our very recent experiments to probe ultrafast dynamics at the Advanced Light Source with high (spectral) resolution soft x-rays and multi-pulse laser excitation.
