Atomic Collisions: We are investigating electron-capture dynamics in collisions of highly-charged ions with neutral atoms. In collaboration with Colorado State University, we have focused our efforts on the use of laser-excited targets and state-of-the-art detection techniques to make novel measurements of energy and angular-momentum distributions of the product states following electron transfer collisions. We are currently developing a Magneto-Optical Trap for Rb to be used in conjunction with a Recoil Ion Momentum Spectroscopy detection scheme to extend the precision of measurements of collision processes.
Atomic Spectroscopy: In an ongoing collaboration with Steven R. Lundeen of CSU, we use laser and microwave spectroscopy to measure the fine structure intervals of multi-electron ionic atoms. The structure constants that are determined are used to check the accuracy of multi-electron calculations. The experiments are done on the ECR ion source facility in the Macdonald lab.
