Hyperfine structure anomaly

The results of research on the NMR spectra of elements with different isotopic composition have been reported. (95) The particular interest of these investigations lies in the possibility of applying perturbation theory to account for the contribution of vibrational states to the shielding of nuclei. (96, 97) In addition, the measurement of nuclear g factors of isotopic pairs, with great accuracy, is required for evaluating small hyperfine structure anomalies. (39,98)... [Pg.317]

For an evaluation of the hyperfine structure anomaly in some atomic states, a reliable ratio of Ca and Ca should be available (G. zu Putlitz, private communication). Therefore... [Pg.301]

This value depends strongly on the correctness of the theory both for the muonium hyperfine structure and the electron magnetic anomaly. Alternatively, extracting a value for a from Avhfs instead represents a most valuable stringent consistency test for different branches of physics, which each allow to obtain a precise value of a (see Fig.3). [Pg.87]

At present the good agreement within two standard deviations between the fine structure constant determined from muonium hyperfine structure and the one from the electron magnetic anomaly is generally considered the best test of internal consistency of QED, as one case involves bound state QED and the other one QED of free particles. [Pg.88]

Fig. 9. The spectroscopic experiments on the hyperfine structure of muonium and the Is-2s energy interval are closely related to a precise measurement of the muon muon magnetic anomaly. The measurements put a stringent test on the internal consistency of the theory of electroweak interaction and on the set of the involved fundamental constants... Fig. 9.

Laser spectroscopic studies of radioactive isotopes have proved to be a valuable source in obtaining nuclear properties. The continuing developments promise a way of meeting challenge in measuring nuclear properties far from stability. It may also be so that new isotopes are discovered by optical rather than nuclear methods. The extreme high precision measurements in ionic traps make rather small nuclear effects such as hype ne anomaly interesting for tx experimental and theoretical studies. In ad(Ution the theories of hyperfine structure and isotope shift are well understood, so that detailed information on nuclear properties can be extracted. [Pg.341]
