Cebaite is a Ba-REE fluoro-carbonate mineral discovered for the first time in the Bayan OboNb-Ta-REE iron ore deposit in Inner Mongolia of China in 1964. Its ideal chemical formula isCe_2Ba_3(CO_3)_5F_2. Since its light and heavy atoms are quite different in proportion and Ba and Ce arequite similar in their X-ray scattering capability, the actural structure of the mineral has not yetbeen accurately determined by means of experiments. In this study we have successively completed
