摘要：

X-ray-diffraction experiments of single-crystal C60 were carried out at temperatures from 300 to 14 K. A small jump in the lattice parameter was observed at the transition temperature T(C) = 260 K, implying that this was a first-order transition. The integrated intensity of the Bragg reflections observed below T(C), which corresponded to the order parameter transformed from the orientational disorder state to the orientational order state, was proportional to the anomalous part of the lattice parameter.
