Fundamental Constants and the Hydrogen Atom

January 1, 2001
Author(s)
Peter J. Mohr, Barry N. Taylor
A review is given of the latest adjustment of the values of the fundamental constants. The new values are recommended by the Committee on Data for Science and Technology (CODATA) for international use. Most of the fundamental constants are obtained by the

CODATA Recommended Values of the Fundamental Physical Constants: 1998

November 1, 2000
Author(s)
Peter J. Mohr, Barry N. Taylor
This paper gives the 1998 self-consistent set of values of the basic constants and conversion factors of physics and chemistry recommended by the Committee on Data for Science and Technology (CODATA) for international use. Further, it describes in detail

Quantum Electrodynamics and the Fundamental Constants

August 1, 2000
Author(s)
Peter J. Mohr, Barry N. Taylor
The fundamental constants are evaluated by comparison of the results of critical experiments and the theoretical expressions of these results written in terms of the constants. Many of the theoretical expressions are based on quantum electrodynamics (QED)

The Fundamental Physical Constants

August 1, 2000
Author(s)
Peter J. Mohr, Barry N. Taylor
The Committee on Data for Science and Technology (CODATA) was established in 1966 as an interdisciplinary committee of the International Council of Science (ICSU, formerly the International Council of Scientific Unions). Soon thereafter, in 1969, CODATA

New NIST Atomic Spectra Database

December 1, 1999
Author(s)
Daniel E. Kelleher, Peter J. Mohr, William C. Martin, Wolfgang L. Wiese, J Sugar, Jeffrey R. Fuhr, Karen J. Olsen, Arlene Musgrove, Joseph Reader, Craig J. Sansonetti, G R. Dalton

Fundamental Constants, QED, and the Proton Form Factor

September 1, 1999
Author(s)
Peter J. Mohr, Barry N. Taylor
Most of the fundamental constants are obtained by the comparison of the results of critical experiments and theoretical expressions for these results. Many of the theoretical expressions are based on quantum electrodynamics (QED), so the consistency of the

The New NIST Atomic Spectra Database (1999)

March 1, 1999
Author(s)
Daniel E. Kelleher, William C. Martin, Wolfgang L. Wiese, J Sugar, Jeffrey R. Fuhr, Karen J. Olsen, Arlene Musgrove, Peter J. Mohr, Joseph Reader, G R. Dalton
The new NIST Atomic Spectra Database (ASD) interactive Web site is accessible via: http://atm.nist.gov/asd. The new version covers a much wider range of atomic and ionic transitions and energy levels than earlier versions, and all data are integrated. ASD

Calculation of the Electron Self Energy for Low Nuclear Charge

January 1, 1999
Author(s)
U Jentschura, Peter J. Mohr, G Soff
We present a nonperturbative numerical evaluation of the one-photon electron self-energy for hydrogen like ions with low nuclear charge numbers Z = 1 to 5. Our calculation for 1S state has a numerical uncertainty of 0.8 Hz for hydrogen and 13 Hz for singly
