Auditory Diagnostic and Prosthetic Devices

September 1, 2001
Author(s)
Victor Nedzelnitsky
This paper is an appendix for the proceedings of the Workshop on Biomedical Materials and Devices, held June 13 -14, 2001. The workshop is part of a series of workshops and topical meetings organized by NIST in the area of biomedical technology. The

Core-Hole-Electron Interaction in X-Ray Raman Scattering

September 1, 2001
Author(s)
J A. Soininen, K Hamalainen, W A. Caliebe, C C. Kao, Eric L. Shirley
This work applies a recently developed first-principles scheme for calculating core-excited states in solids tonon-resonant inelastic x-ray scattering. Within the computational scheme the interaction between the excited electron and the core hole is

Distribution and Retention of 137 Cs in Sediments at the Hanford Site, Washington

September 1, 2001
Author(s)
J P. McKinley, Cynthia J. Zeissler, J M. Zachara, R J. Serne, Richard M. Lindstrom, H T. Schaef, R D. Orr
sium-137 and other contaminants have leaked from many of the single-shell storage tanks at the Hanford Site in southeastern Washington. The leakage was into sandy unconsolidated sediments consisting largely of quartz, plagioclase, micas, smectite, and

Dynamics of Photoinduced Collisions of Cold Atoms Probed with Picosecond Laser Pulses

September 1, 2001
Author(s)
F K. Fatemi, Kevin Jones, H Wang, I Walmsley, Paul D. Lett
Pump-probe experiments are performed in which cold colliding Na atoms are photoassociated to form Na$ _(2)$ molecules, and subsequently ionized. the experiments are performed in a regime where the pulsed photoassociation to an intermediate potential takes

Effects of Wafer Emissivity on Light-Pipe Rediometry in RTP Tools

September 1, 2001
Author(s)
Kenneth G. Kreider, David W. Allen, D H. Chen, D P. DeWitt, Christopher W. Meyer, Benjamin K. Tsai
We investigated the effect of different wafer emissivities and the effect of low emissivity films on rapid thermal processing (RTP) wafer temperature measurements using lightpipe radiation thermometers (LPRTs). These tests were performed in the NIST RTP

Fracture of a Textured Anisotropic Ceramic

September 1, 2001
Author(s)
M H. Zimmerman, D M. Baskin, K T. Faber, Lin-Sien H. Lum, Andrew J. Allen, D T. Keane
The role of crystallographic texture in determining the fracture behavior of a highly anisotropic ceramic, iron titantate, has been examined. By exploiting the anisotropy in its single crystal magnetic susceptibility, crystallographically textured and

Graded Microstructure and Mechanical Properties of Human Crown Dentin

September 1, 2001
Author(s)
W Tesch, Naomi Eidelman, P Roschger, F Goldenberg, K Klaushofer, P Fratzl
The mineralized tissue of intertubular dentin is a collagen-mineral composite with considerable local variations of mechanical properties. Area-scans of human tooth were made by complementary methods to investigate correlations between local mechanical

How Accurately Can Your Interferometer Interpolate Fringes?

September 1, 2001
Author(s)
John R. Lawall
Optical interferometry is the means by which real-world displacements are measured relative to a standard reference wavelength. Most interferometers use a helium-neon laser and generate a signal with a period of half the wavelength, λ/2=316.5 nm. To
