We present a solution to the multiple-scattering inverse problem for low-energy electron diffraction that enables the determination of the
three-dimensional atomic structure of an entire surface unit cell directly from measured data. The solution requires a knowledge of the structure of
the underlying bulk crystal and is implemented by a maximum entropy algorithm. ©2002 The American Physical Society
