Bremsstrahlung-Isochromat study of unoccupied electronic states in R.E.Pd<SUB>3</SUB> compounds

Bremsstrahlung-Isochromat spectroscopy studies of R.E.Pd3 compounds (R.E.=Eu, Yb, Lu) show- in addition to features from unoccupied 4f states- a narrow prominent peak 2.3 to 3.5 eV above EF, which is identified as due to a narrow R.E. d-band state typical for this class of materials. For EuPd3 and YbPd3 BIS spectra of 4f7 and 4f14 final states are reported, at energies in agreement with the 4f-configurational stability of these compounds
