I had same problem with alpha-alumina. The solution was the right occupation numbers. In Fullprof it is the ratio of the multiplicity of special position / general multiciplity of the space group (thanks again to Dr.Roisnel)

However, in the present programe version (2005) rombohedral space group must be given with hexagonal description, which is my starting model. The atom coordinates and unit cell parameters of the hexagonal converted rombohedral structure are correct, however when I try to refine the structure appears a serious problem with the peaks intensity (the preferred orientation is negligible). Has somebody faced such a problem and what could be the solution of it. Many thanks in advance!
