Application of MeV ions to the analysis and modification of high temperature superconducting materials

Description: In analyzing the composition of high {Tc} superconducting materials using heavy-ion RBS we discovered that the electronic excitation of the target caused mixing to occur. To study this effect we made superlattice structures of alternating thin layers of Ba{sub 2}YCu{sub 3}O{sub 6+x} and BaF{sub 2}. At this point in the process some mixing has occurred, but the individual layers are still visible. However, as the bombardment continued the layers were mixed together. It may well be that one can u… more

(High T sub c superconductivity)

Description: A detailed description of the research conducted at the University of Paris at Orsay and the International Meeting on High-{Tc} Superconductivity, organized by the traveler, H. Schultz from Orsay, and D. M. Newns from IBM, is presented. Particular emphasis is placed on the collaboration with F. Perrot of the Centre Europeen de Calcul Atomique et Moleculaire. In addition, descriptions of the different scientific interactions and information obtained and implications of this scientific exchange o… more

Prediction of metal sorption in soils

Description: Radionuclide transport in soils and groundwaters is routinely calculated in performance assessment (PA) codes using simplified conceptual models for radionuclide sorption, such as the K{sub D} approach for linear and reversible sorption. Model inaccuracies are typically addressed by adding layers of conservativeness (e.g., very low K{sub D}'s), and often result in failed transport predictions or substantial increases in site cleanup costs. Realistic assessments of radionuclide transport over a … more
