1#Cerium Niobium Oxide, CeNb04
2#Monoclinic, I2/a (15), Z = 4. The structure of CeNb04 has been determined using neutron
3#powder diffraction by Santoro et al. [1980]. This phase had earlier been reported to be in
4#space group Ia(5) by Komkov [1959]. CeNb04 is isostructural with other rare earth niobates
5#and tantalates [Roth et al., 1977]. The structure is a distorted scheelite type called
6#beta-fergusonite-(Ce) or brocenite [Kuo et al., 1975].
7#Lattice constants of this sample
8#a = 5.5403(7), b =11.4087(14), c = 5.1631(7), beta = 94.602(13)
9#a/b = 0.4856, c/b = 0.4526
