摘要：
In certain endohedral systems a metallic ion is trapped inside C-60 such that the energy minimum corresponds to an off-centre position of the ion. A simple analytical function is proposed to represent the potential-energy curve for such systems. The applicability of this function to potential energy curves of endohedral Na+ and Li+ ions in C-60 is demonstrated and it is then used to calculate the structure of spectra for the two systems.
