Phase Control of Li 2 Wave Packets on Two Electronic Curves

January 1, 2002
Author(s)
H U. Stauffer, J B. Ballard, Z Amitay, S R. Leone
Coherent dynamics of rotational wave packets in two Li 2 electronic states are manipulated using phase-tailored femtosecond pulses. A shaped preparation pulse simultaneously creates wave packets in the A{ 1ς u +) electronic states, subsequently ionized

Phase Diagram of a Nearly Isorefractive Polyolefin Blend

January 1, 2002
Author(s)
Haonan Wang, Charles C. Han, K Shimizu, Erik K. Hobbie, Z G. Wang, J C. Meredith, Alamgir Karim, Eric J. Amis, B S. Hsiao, E T. Hsieh
The phase diagram of coexisting liquid-liquid phase separation (LLPS) and crystallization in nearly isorefractive blends of statistical ethylene/hexane and ethylene/butene copolymers has been investigated. A variety of techniques that exploit

Phase Relationships and Phase Formation in the System BaF 2 -BaO-Y 2 O 3 -CuO x -H 2 O

January 1, 2002
Author(s)
Winnie K. Wong-Ng, Lawrence P. Cook, J Suh, Igor Levin, Mark D. Vaudin, Ron Feenstra, James P. Cline
The interplay of melting equilibria and reaction kinetics is important during formation of the Ba2YCu3O6+x (Y-213) phase from starting materials in the quaternary reciprocal system Ba,Y,Cu//O,F. For experimental investigation of the process we are using a

Phase Separation in Ultrathin Polymer Films

January 1, 2002
Author(s)
Alamgir Karim, Jack F. Douglas, Li Piin Sung, B D. Ermi
Changes in phase separation morphology occurring in thin polymer blend films is discussed. These changes are especially large when the films are thinner than the scale of the bulk material interfacial profile width. Under these circumstances, phase

Photoassociation of sodium in a BEC

C R. McKenzie, J H. Denschlag, H Haffner, A Browaeys, L E. de Araujo, F K. Fatemi, Kevin Jones, J E. Simsarian, D Cho, Andrea Simoni, Eite Tiesinga, Paul S. Julienne, Kristian Helmerson, Paul D. Lett, S L. Rolston, William D. Phillips

Physics Laboratory Annual Report 2001

January 1, 2002
Author(s)
K B. Gebbie, William R. Ott
This report summarizes research projects, measurement method development, calibration and testing, and data evaluation activities that were carried out during calendar year 2001 in the NIST Physics Laboratory. These activities are in the areas of electron

Position Dependence in the CDMS II ZIP Detectors

January 1, 2002
Author(s)
V. Madic, W. Rau, D. S. Akerib, P. Brink, B. Cabrera, J. P. Castle, Fengbo Hang, M. B. Crisler, D. Driscoll, J. Emes, R. J. Gaitskell, J. Hellmig, Martin Huber, S. Kamat, John M. Martinis, P. Meunier, T. A. Perera, M. Perillo-Issac, T. Saab, B. Sadoulet, R. W. Schnee, D. N. Seitz, G. Wang, B. A. Young
The Ge and Si detectors developed by the Cryogenic Dark Matter Search (CDMS) II experiment rely on the simultaneous detection of athermal phonons and ionization produced by interactions in the crystal. The athermal phonons provide both the total energy

V. Madic, W. Rau, D. S. Akerib, P L. Brink, B. Cabrera, J. P. Castle, C S. Chang, M. B. Crisler, D Driscoll, J Emes, R. J. Gaitskell, J. Hellmig, M E. Huber, J M. Martinis, P. Meunier, T. A. Perera, M C. Perillo Isaac, T. Saab, B. Sadoulet, R. W. Schnee, D N. Seltz, G Z. Wang, B C. Young
The Ge and Si detectors developed by the Cryogenic Dark Matter Search (CDMS) 11 experiment rely on the simultaneous detection of athermal phonons and ionization produced by interactions in the crystal. The athermal phonons provide both the total energy

Power Spectral Densities: A Multiple Technique Study of Different Si Wafer Surfaces

January 1, 2002
Author(s)
Egon Marx, I J. Malik, T Bristow, N Poduje, J C. Stover, Y Strausser, M J. Weber
The power spectral density (PSD) formalism is used to characterize a set of surfaces over a wide range of lateral (in-plane, x?y) as well as vertical (out-of-plane, z) dimensions. Twelve 200?mm-diameter Si wafers were prepared; the surface finish ranged

Predicting and Controlling Resource Usage in a Heterogenous Active Network

January 1, 2002
Author(s)
V Galtier, Kevin L. Mills, Y Carlinet, S Bush, A Kulkarni
Active network technology envisions deployment of virtual execution environments within network elements, such as switches and routers. As a result, inhomogeneous processing can be applied to network traffic. To use such technology safely and efficiently
