Abstract: We have studied the structure and stability of Rb⁺Ar_n small clusters (n = 1−20). To describe the potential energy surface of this systems, we have used the analytical form of Tang and Toennies and Lennard Jones (LJ) for the Rb⁺Ar and Ar₂ interactions, respectively. The potential energy surface is explored by the Monte Carlo basin hopping optimisation method in order to determine the minimal structures and their isomers. The relative high stability for Rb⁺Ar_n with n = 6, 10, 12, 18 and 20 is observed.
