Abstract

The electronic structure of metallofullerene Ce@C82 is probed by resonant x-ray emission spectroscopy at the Ce L3 absorption edge. We observed a satellite structure in x-ray absorption and resonant emission spectra for Ce@C82, which, we show, corresponds to the charge transfer induced by the core-hole potential in the final state, similarly to Pr@C82. This charge-transfer satellite may be a common feature in metallofullerenes. The temperature dependence of the electronic structure is also investigated.
