Personal Authentication Through Biometric Technologies

January 1, 2002
Author(s)
Fernando L. Podio
¿¿¿Biometric authentication technologies such as face, finger, hand, iris, and speaker recognition are commercially available today and are already in use. Recent advances in reliability and performance and recent cost drops make these technologies

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

January 1, 2002
Author(s)
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
