Hyperfine frequency
Web3 sep. 2024 · Meanwhile, the hyperfine transition frequency used in Rubidium-87 is around 6.8 GHz while that for Rubidium-85 is around 3.0 GHz. So for a given quality factor, it would appear the clock employing the 3.0 GHz transition would have a smaller linewidth than a 6.8 GHz clock, leading to higher stability.

WebThe uncertainty in the measurement of the mercury hyperfine anomaly is limited by the measurement of the hyperfine frequency ratio. In this paper we will describe an … WebThe hyperfine splitting is due to the interaction of the magnetic moments of the electron and proton, which gives a slightly different magnetic energy for each spin state. These energy …
Astrophysics As the hyperfine splitting is very small, the transition frequencies are usually not located in the optical, but are in the range of radio- or microwave (also called sub-millimeter) frequencies. Hyperfine structure gives the 21 cm line observed in H I regions in interstellar medium. Carl Sagan … Meer weergeven In atomic physics, hyperfine structure is defined by small shifts in otherwise degenerate energy levels and the resulting splittings in those energy levels of atoms, molecules, and ions, due to electromagnetic … Meer weergeven The first theory of atomic hyperfine structure was given in 1930 by Enrico Fermi for an atom containing a single valence electron with an arbitrary angular momentum. … Meer weergeven Hyperfine interactions can be measured, among other ways, in atomic and molecular spectra and in electron paramagnetic resonance spectra of free radicals and transition-metal ions.
