Abstract

EXAFS studies on Rb2CsC60 are made in both the normal and superconducting state. It is found that the contact distance between Rb and C60 and the nth moments 〈(r̂·uRbC)n〉 show anomalous behaviors near the superconducting temperature, where uRbC is the relative displacement. By use of the Einstein model, the frequency is estimated from 〈(r̂·uRbC)2〉 for comparison with recent Raman data.
