Relativistic Many-Body Bound Systems: Electromagnetic Properties

Relativistic Many-Body Bound Systems: Electromagnetic Properties

Date: April 1977
Creator: Danos, Michael
Description: Report presenting the formulae for the calculation of the electron scattering form factors, and of the static magnetic dipole and electric quadrupole moments, of relativistic many-body bound systems. The framework, given in NBS Monograph 147, is relativistic quantum field theory in the Schrodinger picture ; the physical particles, i.e. the solutions of the interacting fields, are given as linear combinations of the solutions of the free fields, called the parton fields. The parton-photon interaction is taken as given by minimal coupling, p -> p - eA ; in addition the contribution of the photon-vector meson vertex of the vector dominance model is derived.

The Dynamics of Fields of Higher Spin

The Dynamics of Fields of Higher Spin

Date: August 1976
Creator: Hayward, Raymond W.
Description: Report presenting a relativistic theory of motion that is free of many of the difficulties common in relativistic equations of motion. This Lagrangian theory describes fields and particles with arbitrary mass and charge and having any discrete spin, integer or half integer.

The First Spectrum of Hafnium (HF I)

The First Spectrum of Hafnium (HF I)

Date: July 1976
Creator: Meggers, William F.
Description: Report continuing W. K. Meggers' previous analysis in LS-coupling. This coupling is not rigorous in Hf I, and many intervals are irregular. Consequently, the levels are given also in numerical order with the even and odd levels presented in separate tables. The long line lists are given in two Appendices: Appendix A contains the observed Zeeman data for the individual lines, 531 in all; Appendix B consists of the complete line list of observed and classified lines. By far the greater part of the analysis is that of Meggers.

Automatic Measurement of Network Parameters: A Survey

Automatic Measurement of Network Parameters: A Survey

Date: June 1976
Creator: Beatty, Robert William
Description: Report issued by the Bureau of Standards over a survey conducted on measurement methods of network parameters. As stated in the introduction, "this paper is concerned with the development of automatic methods of measuring basically the magnitudes and phase differences, or the complex ratio of two sinusoidal voltages, and applications of this capability to determining complex reflection coefficients and transmission coefficients and group delay times of electrical networks" (p. 1). This report includes tables, and illustrations.

Liquid-in-Glass Thermometry

Liquid-in-Glass Thermometry

Date: January 1976
Creator: Wise, Jacquelyn A.
Description: Report containing information of general interest to manufacturers and users of liquid-in-glass thermometers. This report supersedes Monograph 90. Instructions explaining how to submit a thermometer to the National Bureau of Standards for calibration are provided, and the techniques and equipment, such as stirred liquid comparison baths, used in the calibration procedures are described. A discussion of important principles of acceptable thermometer design and factors affecting their use is included. Listed are tables of tolerances reflecting good manufacturing practices and reasonably attainable accuracies expected with liquid-in-glass thermometers. The calculation of corrections for the temperature of the emergent stem is given in detail for various types of thermometers and conditions of use.

A Gage Block Measurement Process Using Single Wavelength Interferometry

A Gage Block Measurement Process Using Single Wavelength Interferometry

Date: December 1975
Creator: Beers, John S.
Description: Report describing the interferometric measurement process using a laser light source and a Kosters type gage block interferometer. Continuous evaluation and refinement of the process is aided by statistical treatment and control chart techniques. All error sources, both random and systematic, are evaluated and the process is maintained in a state of statistical control.
