Precision Study of Hyperfine Structure in Simple Atoms
نویسندگان
چکیده
We consider the most accurate tests of bound state QED theory of the hyperfine splitting in two-body atoms related to the HFS interval of the 1s state in muonium and positronium and the 2s state in hydrogen, deuterium and the helium-3 ion. We summarize their QED theory and pay special attention to involved effects of strong interactions and to recent optical measurements of the 2s HFS interval in hydrogen and deuterium. We present results for specific ratios of the 1s − 2s frequencies in hydrogen and deuterium which happen to be among the most accurately measured and calculated quantities.

We consider the most accurate tests of bound state QED, precision theory of simple atoms, related to the hyperfine splitting in light hydrogen-like atoms. We discuss the HFS interval of the 1s state in muonium and positronium and of the 2s state in hydrogen, deuterium and helium-3 ion. We summarize their QED theory and pay attention to involved effects of strong interactions. We also consider r...
متن کاملHigh-precision measurement of hyperfine structure in the D lines of alkali atoms
We have measured hyperfine structure in the first-excited P state (D lines) of all the naturally-occurring alkali atoms. We use high-resolution laser spectroscopy to resolve hyperfine transitions, and measure intervals by locking the frequency shift produced by an acousto-optic modulator to the difference between two transitions. In most cases, the hyperfine coupling constants derived from our ...
متن کاملPrecision physics of simple atoms: QED tests, nuclear structure and fundamental constants
Quantum electrodynamics is the first successful and still the most successful quantum field theory. Simple atoms, being essentially QED systems, allow highly accurate theoretical predictions. Because of their simple spectra, such atoms have been also efficiently studied experimentally frequently offering the most precisely measured quantities. Our review is devoted to comparison of theory and e...
متن کاملSecond-order effects on the hyperfine structure of P states of alkali-metal atoms
We analyze second-order M1-M1 and M1-E2 effects on the hyperfine structure HFS of the lowest-energy P states of alkali-metal atoms arising from the coupling of the two J=1 /2,3 /2 fine-structure levels through the hyperfine interaction. We find these effects to be especially sizable in Li, leading to a 9 correction to the most accurate reported experimental value of the A P1/2 HFS constant of L...
متن کاملHyperfine Structure of the Ground and First Excited States in Light Hydrogen-Like Atoms and High-Precision Tests of QED
We consider hyperfine splitting of 1s and, in part, of 2s levels in light hydrogen-like atoms: hydrogen, deuterium, tritium, helium-3 ion, muonium and positronium. We discuss present status of precision theory and experiment for the hfs intervals. We pay a special attention to a specific difference, D21 = 8Ehfs(2s) − Ehfs(1s), which is known experimentally for hydrogen, deuterium and He ion. Th...
