Van der Waals molecules consisting of a zinc or cadmium atom interacting with an alkali-metal or alkaline-earth-metal atom

Alkaline-earth-like transition-metal atoms such as Zn and Cd are promising candidates for precision measurements quantum many-body physics experiments. Here, we theoretically investigate the properties of diatomic molecules containing these closed-shell atoms. We calculate potential energy curves, permanent electric dipole moments, spectroscopic constants consisting either a or atom interacting with an alkali-metal (Li, Na, K, Rb, Cs, Fr) alkaline-earth-metal (Be, Mg, Ca, Sr, Ba, Ra) atom. use ab initio electronic structure coupled cluster method single, double, triple excitations combined large Gaussian basis sets small-core relativistic energy-consistent pseudopotentials heavier predict that studied in ground state chemically reactive weakly bound van der Waals complexes small moments. The present results may be useful spectroscopy application modern ultracold chemistry
