The 4f electron excitation spectra for a series of 
compounds with x=0; 0.2; 0.5 and 0.8, where transition occurs from intermediate
valence to a localized 4f state, have been measured at 
K by
inelastic neutron scattering for a wide range of neutron energy transfer. A
qualitative change of the magnetic response takes place when
the hybridization energy becomes nearly equal to the crystal field splitting
of the 4f shell. In pure CeNi, a gap-like magnetic spectrum has been
observed.
