A relaxational process of C60molecules around 90 K between two orientational states was studied. A model of the energy barrier between two orientational states, which depends on the orientational states of neighbor molecules, is proposed. Through the model, the Monte Carlo simulation can describe the relaxational process in the temperature around 90 K. According to the simulation result, the molecules in a 38° state take the curved or pointlike arrangement in the crystal.
