Aqueous biphasic systems for metal separations : a microcalorimetric analysis of polymer/salt interactions.

Description: Certain radionuclide ions (e.g., TcO{sub 4}{sup 16}) exhibit unusually strong Affinities toward the polymer-rich phase in aqueous biphase systems generated by combinations of salt solutions with polymers such as poly(ethylene glycol) (PEG) and poly(propylene glycol) (PPG). Thus, aqueous polymer phases could potentially be used to selectively extract these ions during pretreatment of radioactive tank wastes at Hanford. To help develop a fundamental understanding of the interactions between vario… more

Summary of experimental electroweak physics.

Description: Progress continues on many fronts of experimental testing of electroweak symmetry breaking. Updates were presented on LEP, SLC, Brookhaven g-2 ring, Tevatron Collider, HERA, CESR and Tevatron neutrino experiments. Perhaps most exciting is the Higgs search at LEP2, complementing the indirect constraints. However, the standard model with one Higgs doublet remains viable.

Toward a fourth-generation light source.

Description: Historically, x-ray research has been propelled by the existence of urgent and compelling scientific questions and the push of powerful and exquisite source technology. These two factors have gone hand in hand since Rontgen discovered x-rays. Here we review the progress being made with existing third-generation synchrotron-radiation light sources and the prospects for a fourth-generation light source with dramatically improved laser-like beam characteristics. The central technology for high-bri… more

Russia: Primakov’s Economic Policy Dilemma and U.S. Interests

Description: This report focuses on two divergent scenarios faced by Russia in the wake of its financial crisis of August 1998. Prime Minister Yevgenii Primakov expected either a vicious cycle of decline and possible collapse in government or an economic management scenario following outlines of an agreed action program that makes imperative fundamental changes in the Russian financial system. The success or failure of Russia in dealing with this crisis may have more effect on the pursuit of peace and prosp… more

Ultrafast dynamics of electrons at interfaces

Description: Electronic states of a thin layer of material on a surface possess unique physical and chemical properties. Some of these properties arise from the reduced dimensionality of the thin layer with respect to the bulk or the properties of the electric field where two materials of differing dielectric constants meet at an interface. Other properties are related to the nature of the surface chemical bond. Here, the properties of excess electrons in thin layers of Xenon, Krypton, and alkali metals are… more

Isolating the thermal degree of freedom in nuclear multifragmentation.

Description: Multifragmentation studies induced by GeV light-ion beams permit investigation of the influence of intrinsic thermal properties of hot nuclear matter, with minimal interference from the compression/decompression cycle and rotational instabilities. We summarize recent results obtained with {sup 3}He, proton and pion beams up to 15 GeV/c and present the initial results from a recent experiment with 8 GeV/c antiproton and pion beams. The results are compared with INC simulations coupled to EES and… more

Radiative width of the a {subscript 2} meson

Description: We present data on coherent production of the ({pi}{sup +}{pi}{sup -}{pi}{sup -}) system by 600 GeV/c pion beam in the reaction {pi}{sup -} + A {yields} A + ({pi}{sup +}{pi}{sup -}{pi}{sup -}) for the C, Cu and Pb targets. The Primakoff formalism was used for extracting the radiative width of the a{sub 2} meson. We obtain a preliminary value {Gamma}(a{sub 2}{sup -} {yields} {pi}{sup -}{gamma}) = 225 {+-} 25(stat) {+-} 45(syst) keV.

Neutrino-induced radiation at muon colliders

Description: Intense highly collimated neutrino beams are created from muon decays at high-energy muon colliders causing significant radiation problems even at very large distances from the collider ring. A newly developed weighted neutrino interaction generator permits detailed Monte Carlo simulations of the interactions of neutrinos (and of their progeny) to be performed using the MARS code. Dose distributions in a human tissue-equivalent phantom (TEP) are calculated when irradiated with neutrino beams (1… more

Influence of Rapid Thermal Ramp Rate on Phase Transformation of Titanium Silicides

Description: ULSI technology requires low resistance, stable silicides formed on small geometry lines. Titanium disilicide (TiSiz), which is the most widely used silicide for ULSI applications, exists in two crystallographic phases: the high resistance, metastable C49 phase and the low resistance, stable C54 phase. The major issue with TiSiz is the increasing thermal budget required to transform the C49 phase into the low resistance C54 phase as linewiths decrease below 0.25 pm. Annealing above 900"C to obt… more

W, Z + jets at Tevatron

Description: We report the production jet cross-sections and properties in W and Z events using data from collisions with {radical}s = 1800 GeV at Fermilab Tevatron. Observed distributions in general agree with predictions of leading order QCD matrix element calculations with added gluon radiations and simulated parton fragmentations; however, some limitations of LO QCD predictions are also observed. The cross-section ratio of W + {>=} 1 jet events to inclusive W events is reported and compared with next-to… more
