Eg. Alekseev et al., Quantitative analysis of endohedral metallofullerenes by Rutherford backscattering of protons, TECH PHYS L, 25(5), 1999, pp. 390-392
Samples containing endohedral metallofullerenes of gadolinium (Gd@C-82) and
dysprosium (Dy@C-82) 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 e
ndohedral metallofullerenes Gd@C-82 and Dy@C-82 in samples prepared by sele
ctive multistep extraction is similar to 60%. (C) 1999 American Institute o
