A quantitative look at electron collisions with excited state molecules
Post, September 9, 2026 • The details of electron interactions with excited-state molecules can be important in plasma processes but are experimentally elusive. CRF researchers Jonathan Frank and Dave Chandler, together with postdocs Haw-Wei Lin and Eric Smoll, developed a way to measure these interactions and employed it in their paper "Electron-ionization-dissociation dynamics of laser-excited SO2 (B 1B1/A 1A2) studied using velocity map imaging," published...

Measurements via Double-resonance Ion Imaging Mass Spectrometry
Post, May 27, 2026 • CRF researchers Haw-Wei Lin, Eric Smoll, Jonathan Frank and Dave Chandler published a paper in Journal of Physics B entitled, "Absolute Cross Section Measurements via Double Resonance Ion-Imaging Mass Spectrometry: The mp51/2 n(p′/f′) Autoionizing Rydberg States of Argon." Employing a novel in situ double-resonance scheme using an ion-imaging mass spectrometer...

Transient Pulse-Response for Complex Systems
Post, May 6, 2026 • CRF researchers Nils Hansen, Emma Litzer, and David Osborn, together with colleagues Wenqi Zhou, Alexander R. Morey, Carey Chang and Coleman X. Kronawitter from UC Davis, published a paper on "Transient Pulse-Response Time-of-Flight Mass Spectrometry for Complex, Deactivating Heterogeneous Catalytic Systems: Application to Ethane Dehydroaromatization" in "The Journal of Physical...
