Description
Molecular ions containing heavy nuclei can provide advantages from an experimental and theoretical point of view compared to their neutral counterparts. With ion traps [1] the effective time that can be used for cooling of molecules is increased significantly and after steering the ions through an mass selector one is not necessarily dependent on an additional neutralization process. Meanwhile the accompanying electric charge provides enhanced relativistic effects rendering molecular ions interesting for the search of New Physics [2].
In this contribution, small molecular ions are investigated theoretically in their ground and excited states to explore usability in experiments, laser-coolability and possibility to enhance signatures of New Physics. We show potential energy curves together with relevant molecular properties evaluated together within the two-component zeroth order regular approximation (ZORA).
