Abstract
The probability distribution of the structure factors with non-integral ind ices is derived in P (1) over bar. For integral values of at least one of t he indices, the intensity distribution coincides with that provided by Wils on's statistics, but may strongly differ when the indices ate (or are close to) half-integers. The deviations are stronger when the integral part of t he indices is small, and increase with the size of the structure. In favour able circumstances, moduli and phases of the reflections may be accurately estimated.
