Abstract : The overall theme of this project was to explore methods for using laser-cooled atomic ions to probe information about molecular ions. The initial goal was to focus on the atomic assisted spectroscopy of BH for direct laser-cooling of BH+. In the first year, the direct loading of BH+ remained elusive and the goals were changed to developing spectroscopy techniques for CaH+. These goals included sideband cooling of CaH+, resonance enhanced multiphoton dissociation spectroscopy of CaH+ in a Coulomb crystal, and quantum logic spectroscopy of CaH+. The first two goals have been completed and the third goal is in progress in our lab. We note that NIST Boulder has achieved quantum logic spectroscopy in CaH+ using the results obtained in our lab to design their experiment.
