Precise Energies of Highly Excited Hydrogen and Deuterium

November 1, 2002
Author(s)
Svetlana A. Kotochigova, Peter J. Mohr, Barry N. Taylor
The energy levels of hydrogen and deuterium atoms are calculated to provide frequencies for transitions between highly excited states with principal quantum number n up to 200. All known quantum electrodynamics and relativistic corrections have been

Definitions of the Units Radian, Neper, Bel, and Decibel

August 1, 2001
Author(s)
I M. Mills, Barry Taylor, A J. Thor
The definition of coherent derived units in the International System of Units (SI) is reviewed, and the important role of the equations defining physical quantities is emphasized in obtaining coherent derived units. In the case of the dimensionless

The International System of Units (SI), 2001 Edition

July 1, 2001
Author(s)
Barry N. Taylor
NIST Special Publication (SP) 330 is the United States version of the English text of the definitive international reference on the International System of Units (SI) published by the International Bureau of Weights and Measures (BIPM) on behalf of the

Adjusting the Values of the Fundamental Constents

March 1, 2001
Author(s)
Peter J. Mohr, Barry N. Taylor
In order to compare theoretical predictions to experimental measurements in many basic studies and applications of physics, it is necessary to know the value of one or more of the fundamental physical constants, such as the electron mass, or energy
