Post-Source Decay of Polystyrene Ions in Matrix-Assisted LaserDesorption/Ionization

January 1, 1999
Author(s)
R J. Goldschmidt, S Wetzel, William R. Blair, Charles M. Guttman
Analyte ions produced in matrix-assisted laser desorption/ionization (MALDI) are of low energy compared to those produced in many other mass spectrometricionization methods, so that there is usually little or no prompt fragmentation ofinitially formed ions

Precision Spectroscopy in He as a Test of QED

January 1, 1999
Author(s)
S D. Bergeson, A Balakrishnan, G H. Baldwin, Thomas B. Lucatorto, J P. Marangos, T J. McIlrath, Thomas R. O'Brian, S L. Rolston, Craig J. Sansonetti, J Wen, N Westbrook, C H. Cheng, E E. Eyler

Process Specification Language (PSL): Results of the First Pilot Implementation

January 1, 1999
Author(s)
Craig I. Schlenoff, Michael Gruninger, Mihai Ciocoiu, Donald E. Libes
In all types of communication, the ability to share information is often hindered because the meanig of information can be drastically affected by the context in which it is viewed and interpreted. This is especially true in manufacturing because of the

Quantifying Fire Model Evaluation Using Functional Analysis

January 1, 1999
Author(s)
Richard D. Peacock, Paul A. Reneke, William D. Davis, Walter W. Jones
Comparisons of predictive fire models with each other or with experimental data have been largely qualitative. By treating these time series curves as infinite-dimensional vectors, a branch of mathematics called functional analysis defines geometrically

Quantum Computation, Spectroscopy of Trapped Ions, and Schrodinger Cat

January 1, 1999
Author(s)
David J. Wineland, C Monroe, Wayne M. Itano, D Kielpinski, B E. King, C J. Myatt
We summarize e orts at NIST to implement quantum computation using trapped ions, based on a scheme proposed by J.I. Cirac and P. Zoller (Innsbruck University). The use of quantum logic to create entangled states, which can maximize the quantum-limited

Radiationless Resonant Raman Scattering at the Ar K Edge

January 1, 1999
Author(s)
Thomas W. LeBrun, S H. Southworth, G B. Armen, M A. MacDonald, Y Azuma
Partial cross sections for Ar K-LZL3(1 D2)np, n=4 and 5 spectator Auger states excited by x-ray absorption across the K-edge were measured and compared with calculations based on the theory or radiationless resonant Raman scattering. Core relaxation and
