Ground state hyperfine levels
WebThe definition is: The second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom. [3] In simpler terms, … WebSix γ-ray lines were observed and associated with E2 transitions in the ground state band of 254No, the highest-lying of these being the 16+→ 14+ transition. Based on global systematics and the extrapolated 2+ 1 excitation energy, the value β2= 0.27 ± 0.03 was extracted for the quadrupole deformation.

WebFor example, in 87 Rb, the F’ = 0 and F’ = 3 excited-state hyperfine levels in the 5 P 3/2 state are coupled to only one of the two ground states, due to single-photon selection rules. As a result, a coherence between the two ground states cannot be generated by these levels via CPT, but single-photon transitions out of the CPT state to ...

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 multipole interaction between the nucleus and electron clouds. In atoms, hyperfine structure … See more 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. The Zeeman splitting of this structure was … See more Hyperfine interactions can be measured, among other ways, in atomic and molecular spectra and in electron paramagnetic resonance spectra of free radicals See more • Dynamic nuclear polarisation • Electron paramagnetic resonance See more The theory of hyperfine structure comes directly from electromagnetism, consisting of the interaction of the nuclear multipole moments (excluding … See more 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 … See more • The Feynman Lectures on Physics Vol. III Ch. 12: The Hyperfine Splitting in Hydrogen • Nuclear Magnetic and Electric Moments lookup—Nuclear Structure and Decay Data at the IAEA See more
