2 9 A ug 2 00 5 New limits on the ordered moments in α - Pu and Ga - stabilized δ - Pu

چکیده
We present the first µSR measurements ever performed on elemental Pu, and set the most stringent upper limits to date on the magnitude of the ordered moment µ ord in α-Pu and δ-stabilized Pu (alloyed with 4.3 at. % Ga). Assuming a nominal hyperfine coupling field of 1 kOe/µB we find µ ord ≤ 10 −3 µB at T ∼ = 4 K.

We have calculated the atomic electric dipole moments (EDMs) induced in Hg, Xe, Rn, Ra, and Pu by their respective nuclear Schiff moments S. The results are (in units 10S(e fm)−1e cm): d(Hg) = −2.8, d(Xe) = 0.38, d(Rn) = 3.3, d(Ra) = −8.5, d(Pu) = −11. We have also calculated corrections to the parityand time-invariance-violating (P, T odd) spin-axis interaction constant in TlF. These results a...
متن کاملCoulomb-U and magnetic moment collapse in δ-Pu
– The around-the-mean-field version of the LDA+Umethod is applied to investigate electron correlation effects in δ-Pu. It yields a non-magnetic ground state of δ−Pu, and provides a good agreement with experimental equilibrium volume, bulk modulus and explains important features of the photoelectron spectra. Plutonium is probably the most intricate element from the point of view of condensed mat...

Short-lived nuclides, now extinct in the solar system, are expected to be present in interstellar matter (ISM). Grains of ISM origin were recently discovered in the inner solar system and at Earth orbit and may accrete onto Earth after ablation in the atmosphere. A favorable matrix for detection of such extrater-restrial material is presented by deep-sea sediments with very low sedimentation ra...
متن کاملMultiplet effects in the electronic structure of δ - Pu , Am and their compounds
– We propose a straightforward and efficient procedure to perform dynamical mean-field (DMFT) calculations on the top of the static mean-field LDA+U approximation. Starting from self-consistent LDA+U ground state we included multiplet transitions using the Hubbard-I approximation, which yields a very good agreement with experimental photoelectron spectra of δ-Pu, Am, and their selected compound...
