We have measured XAS and MCD spectra at Ce L $_{2,3}$ -edges in Ce(Fe $_{1-x}$ Co $_{x}$ ) $_{2}$ . All the XAS spectra around the Ce-L $_{3}$ edge exhibit a double-peak structure that is the characteristic feature of the mixed-valence system. The ratio of the 4f $^{1}$ peak intensity to the 4f $^{0}$ peak intensity in the Ce L $_{2,3}$ -edges increased as the composition of Co increased. But the MCD and XAS spectral shape changed slightly for Ce(Fe $_{1-x}$ Co $_{x}$ ) $_{2}$ . As the Co composition increased, MCD intensity decreased. Applying to Sum rules, we found that the orbital magnetic moment of Ce-5d electrons is very small but does exist.
