摘要：

The excited singlet states (n = 2-6) of He atoms interacting with an aluminum surface are studied with the Coupled Angular Mode (CAM) method, which provides their energy positions and widths as functions of the atom-surface distance. The results show very strong couplings between the various states inside each manifold, induced both by direct couplings and indirect couplings via the metal states. These couplings can lead to an attraction as well as to a repulsion of the interacting states. The state mixing results in the formation of hybrids with a rather small width.
