Abstract
Magnetic neutron spectra as a function of temperature are presented for the intermediate-valence compounds Ce, Ce, Ce, Yb, and TmSe. All compounds show the normal local 4 form factor but a broadened magnetic energy spectrum with an overall width of about 7 to 30 meV and with very little temperature dependence (except TmSe). Closer analysis reveals a residual crystal-field spectrum in Yb which may also underlie the spectra of the other compounds. A detailed description of the data analysis is given.
