摘要：
Samples containing endohedral metallofullerenes of gadolinium (Gd@C82) and dysprosium (Dy@C82) are investigated by the Rutherford backscattering of protons. It is shown that the concentration of endohedral metallofullerenes can be determined to within a few percent. The measured concentration of endohedral metallofullerenes Gd@C82 and Dy@C82 in samples prepared by selective multistep extraction is ∼60%.
