Rotational Signatures of Chemical Agents and Related Compounds

January 1, 2000
Author(s)
R D. Suenram, Angela R. Hight Walker, Gerald T. Fraser, David F. Plusquellic, R S. DaBell, Pamela M. Chu, George C. Rhoderick, A C. Samuels, J O. Jensen, Pavol Krivosik, J M. Lochner
The rotational spectra of more than twenty different chemical-warfare agents, precursors, and decomposition products have been studied using the technique of Fourier-Transform MicroWave (FTMW) spectroscopy. The compounds studied include the four common G

Scalable Entanglement of Trapped Ions

January 1, 2000
Author(s)
C Monroe, Q A. Turchette, D Kielpinski, B E. King, V Meyer, Wayne M. Itano, David J. Wineland, C J. Myatt, M A. Rowe, Christopher Langer, C A. Sackett
Entangled states are both a crucial component in quantum computers, and of great interest in their own right, highlighting the inherent nonlocality of quantum mechanics. As part of the drive toward larger entangled states for quantum computing, we have

Second Intercomparision of Radiation Temperature Scales Among Four National Metrological Laboratories Using a Transfer Standard Radiation Thermometer

January 1, 2000
Author(s)
F Sakuma, H Sakate, Graham Machin, J Fischer, Charles E. Gibson, B. Carol Johnson
Round-robin measurements with a transfer-standard radiation thermometer were organized by the National Research Laboratory of Metrology NRLM with the National Institute of Standards and Technology (NIST), National Physical Laboratory (NPL), IMGC (Institute

Seismic Rehabilitation Design of Steel Moment Connection with Welded Haunch

January 1, 2000
Author(s)
Q -. Yu, Chia-Ming Uang, John L. Gross
This paper describes a design procedure for the seismic rehabilitation of pre-Northridge steel moment connections using a welded haunch. Experimental results from cyclic testing of full-scale specimens demonstrated that welding a triangular haunch beneath

SEMPA Imaging of Domain Dynamics in Amorphous Metals

January 1, 2000
Author(s)
A Gavrin, John Unguris
We show how Scanning Electron Microscopy with Polarization Analysis (SEMPA) may be used to observe domain wall motion in amorphous ferromagnetic ribbons commonly used in transformer cores. SEMPA images were obtained from both the smooth, air side of the
