The measured point-contact spectra (directly proportional to the electron-quasi particle interaction function) of the heterocontact between oriented hexagonal single crystal of ferromagnetic NdNi5 and Cu in ballistic and thermal regime are presented above and below TC. At TC = 7 K maxima observed at characteristic energies around 1.5 and 4 meV are of crystal field (CEF) origin. Below TC the splitting of CEF levels by the exchange field is observed. This splitting is consistent with CEF and exchange parameters previously determined.
