| Abstract: | The electron-phonon interaction in LaNi5 is studied by point-contact spectroscopy. The spectrum corresponding to the electron-phonon interaction function g (the phonon density of states modulated by the matrix element of the electron-phonon interaction) is found. The functiong is used to analyze the point-contact spectra of PrNi5, where besides the electron-phonon contribution there is also an interaction between the conduction electrons and the crystal electric field levels of the Pr3+ ion. |
