Abstract

Atoms whose nuclei have an exotic number of nucleons can have a `core nucleus' surrounded by a `halo' formed by a nucleon orbiting the core nucleus. For example, due to the two halo neutrons orbiting the core nucleus of $^{11}$Li, its nucleus has a cross section that is roughly the same size as that of $^{208}$Pb. Halo nucleic atoms have been studied extensively both in theory and in experiments, however halo nucleic molecules have not been studied in either. We first show, using HeH$^+$, BeH, and MgH as examples, that with measurements of any two isotopologues of a molecule, we can determine crucial properties of a third isotopologue well within spectroscopic accuracy. We then use the extremely precise empirical information available\footnote{R. J. Le$\,$Roy, N. S. Dattani, J. A. Coxon, A. J. Ross, P. Crozet, C. Linton, \textit{J. Chem. Phys.} \textbf{131}, 204309 (2009).}$^,$\footnote{N. S. Dattani, R. J. Le$\,$Roy, \textit{J. Mol. Spec.} \textbf{268}, 199-210 (2011).}$^,$\footnote{M. Semczuk, X. Li, W. Gunton, M. Haw, N. S.

We believe that our predictions of the ro-vibrational energies are reliable for experiments for the first detection of a halo nucleic molecule.
