In the present work, we study the electron correlation effects in the electronic structure and spectra of Pu-Am, Pu-Ce alloys and PuCoGa5. We make use of the “local density matrix” approximation (LDMA) to DMFT, that combines the Hubbard-I approximation with the full-potential linearized augmented plane wave (FP-LAPW) method , including self-consistency over the charge density. Calculated PE...

In the U-Pu phase diagram a mysterious ζ-U-Pu phase exists over a large composition range (35-70 % U). This cubic (rhombohedrally distorted) phase has 10 different crystallographic positions, randomly occupied by U and Pu. When compared with other Pu allotropic phases, its volume density of 18.55 g/cm3 fits about half way between a-(19.92 g/cm3 ) and b-Pu (17.70 g/cm3).This value is much...
