The structural determination of endohedral metallofullerene Gd@C_(82) by XANES

摘要

Although the Gd ion in Gd@C_(82) has been shown to lie above the C-C bond on the C_2 axis as an anomalous structure from the MEM/Rietveld analysis, the present XANES study reveals that it lies above the hexagon on the C_2 axis as a normal structure, and Gd oscillates around its equilibrium position with an amplitude increasing with temperature increase.
