Abstract
We propose an approximation Va(r) for the Van der Waals interaction V(r) between an atom and a non-planar solid. Va(r) is both simpler to compute than V(r) and of considerably more convenient form. The approximation is found to be quite good except for very large z (the atom-surface separation). In the latter case, our comparison of Va and V permits one to estimate corrections to Va.
