A theory is developed for the temperature dependence of crystal field energy levels of Ce ions in metals caused by the Kondo effect. Abrikosov's pseudofermion technique is applied to the Coqblin-Schrieffer exchange model, and the self energy is derived in the self-consistent ladder approximation. The neutron quasi-elastic and inelastic scattering spectra are calculated in the system with cubic crystal field.
