摘要：

The comparison of the characteristic point-contact spectra of heterocontacts 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 interaction to the electron-quasiparticle interaction function is qualitatively similar. 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.
