The model of an atom confined in a semi‐infinite space with a plane boundary allows the variational evaluation of the ground‐state energies and wavefunctions for He and at different positions from the surface. The respective Born‐Oppenheimer energy curves serve to model the ground‐state energy shift for the elastic scattering channel in atom (ion)‐surface interactions. Comparison with recent experimental evidence of an energy shift of the He ground‐state as a function of distance from an aluminum surface is presented. Further validation of the model is analyzed taking as reference pilot calculations based on Electron Nuclear Dynamics for the elastic channel in He ‐benzene molecule interactions.
