State-Selective Ionization and Trapping of Single H${}_2^{+}$ Ions with (2+1) Multiphoton Ionization

Ho June Kim, Fabian Schmid, David Holzapfel +1

We report on efficient rovibrational state-selective loading of single H${}_2^{+}$ molecular ions into a cryogenic linear Paul trap using (2+1) resonance-enhanced multi-photon ionizati…
