摘要：

LEED I(V) data comprising three non-degenerate beams have been collected at normal incidence from the cleaved (001) surface of TiO2. Care has been taken to minimize the effects on the I(V) data of electron beam damage to the surface. Analysis of the I(V) data has been carried out using tensor LEED theory and a search strategy designed to minimize the Pendry R-factor. A wide range of possible structures has been examined including a model proposed using energy minimization techniques. The trial structures have included distortions in up to three layers of the surface. Data on two likely structural solutions are presented.
