Abstract Surface structure analysis is now 25 years old but we still know little about the structure of surfaces, at least when we use the first 25 years of structure analysis of the bulk for comparison. The reason for the slow progress is obvious when we compare the techniques with which the two fields started; X-ray diffraction and low-energy electron diffraction (LEED). In the first case the interaction with the sample is weak which makes a simple analysis possible, e.g., in terms of the first Born approximation (kinematic theory, single scattering), in the second case the interaction is strong so that the weak interaction approximations break down.
