Electronic structure of superconducting UBe13
Physical Review B (Condensed Matter)
We have studied the actinide superconductor UBei3 with resonant photoemission using synchrotron radiation 30 «hv «120 eV. In agreement with the anomalously high y value of 1.1 J/mole K2, we find a high density of 5 f states at the Fermi level EJ;. Uranium 6d electrons are not present at EJ; as can be derived from the zero intensity at EF in the off-resonance spectrum. The close resemblance of this off-resonance curve to a photoemission spectrum of pure Be suggests that the hybridization of U Sfdoi:10.1103/physrevb.29.493 fatcat:lxoisnjx6faojb2uihuhvtz3bi
