Hyperfine Structure Constants for Diatomic Molecules

March 1, 1998
Author(s)
I Tupitsyn, Svetlana A. Kotochigova
The contact term A c of magnetic hyperfine parameters as a function of internuclear distance R was computed, using the all-electron Valence-Bond method, Hartzee-Fock atomic basis set and configuration-interaction wave functions. Parameters were calculated

Integration Strategies for the Reactive Scheduling System

March 1, 1998
Author(s)
David W. Thomas
Shop Floor operations can be optimized by scheduling applications that not only create an initial schedule but also allow feedback from data collection systems to enable re-scheduling. Interfaces required to integrate the various commercial applications

Multiple Fiber Technique for the Single Fiber Fragmentation Test

March 1, 1998
Author(s)
Chang K. Moon, Walter G. McDonough
The single fiber fragmentation test has been modified by embedding multiple fibers into matrix resin. During testing, we examined the interfacial shear strengths between the fibers and the matrix. In addition, the time-dependent nature of the fragmentation

National Semiconductor Metrology Program, Project Portfolio, FY 1998

March 1, 1998
Author(s)
Stephen Knight, A D. Settle-Raskin
The National Semiconductor Metrology Program (NSMP) is a NIST-wide effort designed to meet the highest priority measurement needs of the semiconductor industry as expressed by the National Technology Roadmap for Semiconductors and other authoritative

NIST Meeting on Multicomponent Polymers and Polyelectrolytes

March 1, 1998
Author(s)
Jack F. Douglas
A joint meeting was held between the NIST Polymer Blends and Processing Group and ERATO. The purpose of the conference was to review progress made by the NIST and ERATO groups in experimental and theoretical aspects of phase separation in polymer blends

NIST Methods for the Certification of SRM 1941a, Organics in Marine Sediment, and SRM 1974a, Organics in Mussel Tissue (Mytilus edulis)

March 1, 1998
Author(s)
Michele M. Schantz, Bruce A. Benner Jr, M K. Donais, M. J. Hays, William R. Kelly, Reenie M. Parris, Barbara J. Porter, Dianne L. Poster, Lane C. Sander, Katherine E. Sharpless, Robert D. Vocke Jr., Stephen A. Wise, M Levenson, Susannah B. Schiller, M Vangel
The replacement Standard Reference Materials [SRM 1941, Organics in Marine Sediment, and SRM 1974, Organics in Muscle Tissue [Mytilus edulis], have been prepared and analyzed for the determination of trace organic constituents. SRM 1941a has been issued

Optical Computer Aided Tomography of an Inductively Coupled Discharge

March 1, 1998
Author(s)
Eric C. Benck, J R. Roberts
Optical computer aided tomography (CAT) is being investigated as a potential in situ diagnostic for measuring plasma uniformity without making assumptions concerning the plasma symmetry. The presence of an opaque vacuum chamber wall severely limits the

Personal Identification From Mugshot Ear Images

March 1, 1998
Author(s)
F E. McFadden
This work establishes the high value of ear images for personal identification from mugshot data, using the NIST database of police mugshots. It starts with a method for boundary analysis based on two innovations. First edge analysis is performed only

Round Robin Determination of Power Spectral Densities of Different Si Wafer Surfaces

March 1, 1998
Author(s)
Egon Marx, I J. Malik, Y Strausser, T Bristow, N Poduje, J C. Stover
Power spectral densities (PSDs) were used to characterize a set of surfaces over a wide range of lateral as well as perpendicular dimensions. Twelve 200-mm-diameter Si wafers were prepared and the surface finishes ranged from as-ground wafers to epitaxial

Small Angle Scattering by Dislocations

March 1, 1998
Author(s)
R Thomson, Lyle E. Levine, Gabrielle G. Long
It is shown that the small-angle scattering of x rays or neutrons by dislocations in a deformed metal, which are partially ordered into wall-like structures, is characterized by several structure factors. Principally there are associated with 1) a single
