The authors thank Dr. Tomoya Uruga of JASRI for his valuable suggestions concerning XAFS and XANES measurements. They are also grateful to Dr. Takashi Yamamoto of Kyoto University for his valuable discussion on XANES and to Dr. Osamu Kamishima of Tohoku University for his valuable suggestion on XAFS analysis. Further, they are indebted to Prof. Tadao Ishii of Okayama University for his valuable discussion on thermal behavior estimated from XAFS. This work was achieved under a proposal of SPring-8 (1999B0331-NX) and was supported by a Grant-in-Aid (11165227) from the Ministry of Education, Science, Sports and Culture, Japan.

N2 - The structure of La2@C80 is studied by La K-edge XAFS from 40 to 295 K. The distances between the La atom and the first nearest C atoms have been determined to be 2.42(1) Å at 40 K and 2.44(2) Å at 295 K, and those between the La atom and the second nearest C atoms to be 2.97(2) Å at 40 K and 2.98(3) Å at 295 K. The La-La distance has been determined to be 3.90(1) Å at 40 K and 3.88(2) Å at 295 K. The temperature dependence of the mean-square displacement of La-C is also studied to get an insight into the dynamical behavior of two La atoms in the C80 cage.
