By comparing it with the atomic scattering factor of carbon,it is found that the scattering factor of C60 molecule is a sine-oscillating attenuate finction of sinθ/λ depending on the direction of the incident beam, which is attenuatedmore quickly than that of single carbon atom. However, there is nO evident differencefor the different directions when 0.00≤sinθ/λ≤0.15.展开更多

The temperature-dependent solubillty of C60 displays the anomalous behavior. A solubility maximum of C60 around O℃ for toluene and CS2, and around 30℃ for o-xylene was observed. The temperature-dependent solu bility of C70 displays the normal behavior in the same solvents.展开更多
