Abstract
The comparison of the characteristic point-contact spectra of heterocontact s between RENi5 (RE = La, Ce, Pr, Nd, Sm, Dy, Y) and Cu is presented. It is shown that in all samples the contribution of the electron-phonon interact ion to the electron-quasiparticle interaction function is qualitatively sim ilar. This observation reflects the very similar lattice constants for all RENi5 and supports the manner of subtracting the phonon parr of electrical resistivity of bulk RENi5 samples.
