Sm-Nd systematics of Earth are inconsistent with a superchondritic Sm/Nd ratio
The relationship between the compositions of the Earth and chondritic meteorites is at the center of many important debates. A basic assumption in most models for the Earth’s composition is that the refractory elements are present in chondritic proportions relative to each other. This assumption is now challenged by recent Nd/Nd ratio studies suggesting that the bulk silicate Earth (BSE) might ...
متن کاملSm-Nd Isotopic Data and Earth's Evolution.
Samuel A. Bowring and Todd Housh (1) report Sm/Nd isotopic data giving a wide range of initial ENd values, from +3.5 to -4 at 4.0 billion years ago (Ga) and from +4 to -7 at 3.6 Ga. Their samples were from the Acasta gneisses of northern Canada, which represent the oldest known outcrops of continental crust (2). Their modeling of the Sm-Nd isotopic data is taken to suggest that the Acasta grani...
متن کاملStudy of shape transitions in N ∼ 90 isotopes with beyond mean field calculations
We study the spherical to prolate-deformed shape transition in 144−158Sm and 146−160Gd isotopes with modern calculations beyond the mean field with the Gogny D1S force. We compare the results with the shape-phase transition predicted by the collective hamiltonian model and with the experimental data. Our calculations do not support the existence of a first order phase transition in these isotop...

متن کاملSingle-Ion Anisotropy, Crystal-Field Effects, Spin Reorientation Transitions, and Spin Waves in R2CuO4 (R=Nd, Pr, and Sm)
We report a detailed study of single-ion anisotropy and crystal-field effects in rare-earth cuprates R2CuO4 (R=Nd, Pr, and Sm). It is found that most of the magnetic properties are mainly due to the coupling between the copper and rare-earth magnetic subsystem which exhibits a large single-ion anisotropy. This anisotropy prefers ordering of rare-earth moments along [100] for R=Pr and Nd and alo...
