Kondo side bands

Fermi energy. The latter set of peaks can be categorized as a set of crystal field Kondo side bands with excitation energies of... 

Since all of these f photo-emission peaks are side bands of the basic Kondo peak, they are all proportional to the weight of the/° component in the ground state That is, the Kondo peaks represent processes whereby a single electron is added to the f level (for C/ff oo this requires the presence of an imoccupied f orbital in the initial state), the intensities of the side bands are all proportional to (1 - f). As the peaks do not have simple Lorentzian forms, they are asymmetric the total intensities are not straightforward to estimate. However, by assuming a Lorentzian shape, we have the estimates of the integrated intensities of the crystal field split Kondo side bands given by the expressions... 

The three spin-orbit split Kondo side bands have intensities that are estimated to be...
