An atomic unit of length used in quantum mechanical calculations of electronic wavefunctions. It is symbolized by o and is equivalent to the Bohr radius, the radius of the smallest orbit of the least energetic electron in a Bohr hydrogen atom. The bohr is equal to where a is the fine-structure constant, n is the ratio of the circumference of a circle to its diameter, and is the Rydberg constant. The parameter a includes h, as well as the electron s rest mass and elementary charge, and the permittivity of a vacuum. One bohr equals 5.29177249 x 10 meter (or, about 0.529 angstroms).

Recently we have used the femtosecond technology to measure the transition frequency of the cesium Di line [45]. This line provides an important link for a new determination of the fine structure constant a. Because a scales all electromagnetic interactions, it can be determined by a variety of independent physical methods. Different values measured with comparable accuracy disagree with each other by up to 3.5 standard deviations and the derivation of the currently most accurate value of a from the electron g — 2 experiment relies on extensive QED calculations [46], The 1999 CODATA value [47] or1 = 137.035 999 76(50) (3.7 x 10-9) follows from the g — 2 results. To resolve this unsatisfactory situation it is most desirable to determine a value for the fine structure constant that is comparable in accuracy with the value from the g — 2 experiment but does not depend heavily on QED calculations. A promising way is to use the accurately known Rydberg constant i oc according to ... 

The two-photon 243 nm lS S-i/2 transition and other transitions in the hydrogen atom have recently been included in a new list of approved radiations for the practical realisation of the metre [2]. The particular interest of these transitions lies in the fact that, uniquely among present optical frequency standards, they may be calculated in terms of the Rydberg constant with an accuracy approaching that with which they have been measured. The latest measurement of... 

The Rydberg constant is the scale factor that connects all theoretical calculations and experimental measurements of energy levels in any system involving electrons. This includes all atoms, molecules and condensed matter. In simple systems, such as hydrogen, positronium, muonium, and possibly helium, the theoretical accuracy is comparable to that of experiments. In this case, experimenters can be said to measure the Rydberg constant, if not to test theory. 

Laser spectroscopy, at the moment, is the method par excellanoe to measure R. Measurement of the Rydberg constant R is a simple matter. One measures the wavelength or frequency (the velocity of light is defined to be 299 792 1)58 m/sec) in a system, such as hydrogen, where theoretical calculations are expected to be accurate to within the experimental error. One then compares this measurement (in Hz or cm-1) with the theoretical calculation (in atomic units), thereby finding the atomic unit in Hz or cm-1. Half of the atomic unit is the Rydberg... 

The Rydberg constant is a constant that meets all the criteria established for being deemed fundamental. In addition, the Rydberg constant connects all theoretical calculations and experimental measurements of the energy states of any atom.

The Is-2s transition energy is primarily due to the (electron) Rydberg constant, where the antiproton mass contributes via the reduced mass only of the order of 10 . For the theoretical calculations an uncertainty exists at the level of 5 X 10 [17] (finite size corrections) due to the experimental error in the determination of the proton radius, even if only the more rehable Mainz value of = 0.862 0.012 fm [18] is used (for a detailed discussion of the pro-...
