Abstract–

Anticommutator Green functions and energy spectra of fullerene C₂₆ and endohedral fullerene U@C₂₆ with D_3h symmetry groups are obtained in the analytical form within the Hubbard model and static fluctuation approximation. The energy states are classified using group theory methods; allowed transitions in the energy spectra of C₂₆ and U@C₂₆ molecules with D_3h symmetry group are determined.

Hubbard模型中富勒烯С26的能谱和光吸收谱

摘要-

_{富勒烯C 26}和具有D _{3 h}对称群的内嵌富勒烯U@C ₂₆的反对子格林函数和能谱以Hubbard模型内的解析形式和静态波动近似得到。使用群论方法对能量状态进行分类；确定了具有D _{3 h}对称群的 C ₂₆和 U@C ₂₆分子的能谱中允许的跃迁。
