The crystal field splitting of the 3 H 4 ground state multiplet of Pr 3+ in PrNi 2 is studied by inelastic neutron scattering (TOF). The crystal field parameters are found to be B 4 0= (24.5 ± 1.8) × 10 −4 meV and B 6 0= – (65.7 ± 6.9) × 10 −6 meV. The ground state is the nonmagnetic Γ 3 doublet. The derived crystal field level scheme is proved by measuring the specific heat. From magnetic measurements the molecular field constant λ = 67 kOe/μ B and from the temperature dependence of the thermoelectric power the direct scattering potential of the conduction electrons V = –0.057 eV and the exchange coupling parameter J 11 = –0.029 eV are derived.
