- Abstract
- Reactions of laser-cooled Ca$^{+}$ and Ba$^{+}$ ions with O$_{2}$ provide pathways to the formation of cold molecular cations (CaO$^{+}$ and BaO$^{+}$) that may be further manipulated using ion trapping techniques. Spectroscopic data for these ions are needed to facilitate the characterization of internal state population distributions using highly sensitive detection schemes such as resonantly enhanced multi-photon dissociation (REMPD). Ab initio electronic structure calculations predict that both ions have X$^{1}$$\Sigma$$^{+}$ ground states, accompanied by low-lying A$^{2}$$\Pi$ states. We are currently using two-color photoionization techniques to observe the low-lying ro-vibronic states of CaO$^{+}$ and BaO$^{+}$. The neutral molecules are produced by laser ablation of the metals, combined with free-jet expansion driven by He/O$_{2}$ (0.1-0.2\%) mixtures. Photoionization efficiency curves and zero kinetic energy photoelectron spectra will be reported.
