Abstract
It is shown that interaction with crystal-field excitations can cause a pseudogap to appear in the spectrum of heavy-fermion compounds with a nearly integer valence. The necessary conditions for the appearance of a pseudogap are formulated and it is demonstrated that these condit ions are realized in the compound CeNiSn. Suppression of the pseudogap by an external magnetic field is studied.
