17. The expression of Eq. 6 is slightly different from the exchange energy by Jo and Imada (Ref.) and by Matsuyama (Ref.) because they used the LS coupling scheme for the Ce4f states but we use the JJ coupling scheme. In describing the Ce4f states, the JJ scheme is better than the LS scheme due to the strong spin-orbit coupling, but the effect of the exchange energy on the XMCD spectrum is not seriously different in the two schemes.
18. The factor [1-α Eex (md, sd; j, jz)] in Eq. (9) of Ref. is a misprint for [1-α Eex (md, sd; j, jz)] 1/2.
19. To be more exact, the function f j′, j, jz (ω) includes the ground-state energy Eg, which depends on the mixed-valence character of the ground state. However, Eg causes only a shift of f j′, j, jz (ω) and gives no influence on the spectral shape and intensity.
