HALO NUCLEIC MOLECULES: MOLECULES FORMED FROM AT LEAST ONE ATOM WITH A HALO NUCLEUS. EMPHASIS ON 11,11Li2 ALONG WITH OTHER EXOTIC ISOTOPOLOGUES.

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 Li, its nucleus has a cross section that is roughly the same size as that of 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 availablea,b,c,d for the low-lying states of Li2, Li2 and Li2 to predict potentials and various properties of the halo nucleic molecule Li2, along with isotopologues containing Li, Li, Li, Li, Li, Li, and Li. We believe that our predictions of the ro-vibrational energies are reliable for experiments for the first detection of a halo nucleic molecule.
