摘要：

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 Schrodinger equation for the triatomic system is solved in the adiabatic approximation. A bound state is found for each of the He-3-He-3-Rb-85, He-3-He-4-Rb-85, and He-4-He-4-Rb-85 trimers, respectively. The bound state for the He-3-He-3-Rb-85 molecule is a Borromean state found in a realistic molecular systems because there are no bound states in both the He-3-He-3 and He-3-Rb-85 dimers.
