Crystal field levels of Pr3+ in PrFeO3 and PrGaO3 determined by inelastic neutron scattering

The crystal field splitting of the 3H4 ground state of the Pr ion in PrFeO3 and PrGaO3 has been investigated by inelastic scattering of thermal neutrons. At several temperatures the transitions have been measured by TAS and TOF methods for polycrystalline PrFeO3 and by the TOF method for polycrystalline PrGaO3. Energy level schemes which are different for these materials are given. [Russian Text Ignored]
