摘要
本文提出固体Ｃ_６０分子间合理的相互作用势模型，利用对称性适配函数描述了晶体场及取向模间耦合，并通过自由能的计算得出相交模及与实验相符的取向相变温度．
Abstract An intermolecular interaction model is proposed in solid C_6o. The crystal field and coupling of librational modes are well formulated by symmetry-adapted rotator functions. The soft modes are obtained by considering the free energy of orientation-orientation coupling.The calculated orientational phase transition temperature agrees with experiments'result.
