Abstract

Eu L_III-edge XAFS spectrum for EuC₆₀ was measured at room temperature in order to clarify the position of the Eu atom. The distances between the Eu atom and the neighboring C atoms determined by XAFS showed clearly that the Eu atom was in the inside of C₆₀ cage, and located on the off-center by 1.4 Å. A XANES spectrum showed that the Eu atom took the mixed valence states of +2 and +3.
