A theoretical binding - energy difference can be obtained using an electrostatic model that has been applied to other ionic components [ 25 ] and values from the literature for the madelung constants [ 26 ] and c60 polarizability [ 27 ] . [ p9872l ] 结合能的差异理论上可以从适用于其它离子成分[ 25 ]的静电模型估算出来，这里需要的数据是文献中的马德隆能常数[ 26 ]和c60的极化率[ 27 ] [ p9872l ] 。
