Description

We search for the existence of weakly bound He-He-Rb molecules. The He-He-Rb molecule is treated as a three-body system. By using hyperspherical coordinates, the Schroedinger equation for the triatomic system is solved in the adiabatic approximation. A bound state is found for each of the 3He-3He-85Rb, 3He-4He-85Rb, and 4He-4He-85Rb trimers, respectively. The bound state for the 3He-3He-85Rb molecule is a Borromean state found in a realistic molecular systems because there are no bound states in both the 3He-3He and 3He-85Rb dimers.
