Imaging of Acoustic Surface Wave Slowness

Author(s)
D Xiang, Nelson N. Hsu, Gerald V. Blessing
An experimental method has been devised for imaging the acoustic surface wave slowness (inverse of the phase velocity) in anisotropic solids. This technique...

The critical evaluation of a comprehensive mass spectral library

Author(s)
C L. Clifton, S G. Lias, Anzor I. Mikaia, Stephen Stein, Dmitrii Tchekhovskoi, O D. Sparkman, Vladimir G. Zaikin, Damo Zhu
A description of methods used to build a high quality, comprehensive reference library of EI mass spectra is presented

Local Environments of Three Forms of Ba2Ycu3O6+x

Author(s)
Winnie K. Wong-Ng, M Melamud, Lawrence H. Bennett
The Wigner-Seitz local atomic cell construction procedure, provides a topological means for comparing series of related structures in terms of the number and...

The NIST Watt Balance: Recent Results and Future Plans

Author(s)
David B. Newell, Richard L. Steiner, Edwin R. Williams
The last remaining SI base unit defined by an artifact is the kilogram. The NIST watt balance has been designed to measure the ratio of mechanical to electrical...

Myths About Building Envelopes

Author(s)
Andrew K. Persily
It is often assumed that commercial and institutional buildings are fairly airtight and that envelopee air leakage does not have a significant impact on energy...

Theory for Ionization of Molecules by Electrons

Author(s)
Yong Sik Kim, M E. Rudd
A simple yet effective theory for the total ionization cross sections of molecules by electron impact is described. The theory, called the Binary Encounter...

Four-Wave Mixing With Matter Waves

Author(s)
Lu Deng, Edward W. Hagley, J Wen, M Trippenbach, Y B. Band, Paul S. Julienne, J E. Simsarian, Kristian Helmerson, S L. Rolston, William D. Phillips
The advent of the laser as an intense, coherent light source gave birth to nonlinear optics, which now plays an important role in many areas of science and...

A Well Collimated Quasi-Continuous Atom Laser

Author(s)
Edward W. Hagley, Lu Deng, M M. Kozuma, J Wen, Kristian Helmerson, S L. Rolston, William D. Phillips
We demonstrate extraction of sodium atoms from a trapped Bose-Einstein condensate (BEC) using a coherent stimulated Raman process. Optical Raman pulses drive...

Ultrafast Glimpses at Water and Ice

Author(s)
Edwin J. Heilweil
Recent literature reports of transient infrared hole-burning and spectroscopic measurements on water and ice are critically reviewed. Dynamical measurements on...

Optical Linewidth Models - Then and Now

Author(s)
Robert D. Larrabee, Richard M. Silver, M P. Davidson
In the late 1970's Dr. Diana Nyyssonen demonstrated that the National Institute of Standards and Technology (NIST) could optically calibrate photomask linewidth...
