What is hyperfine levels of ground state?

What is hyperfine levels of ground state?

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 interaction between the nucleus and electron clouds.

What is unperturbed ground state hyperfine frequency?

It is defined by taking the fixed numerical value of the caesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s-1.

What is the meaning of hyperfine?

: being or relating to a fine-structure multiplet occurring in an atomic spectrum that is due to interaction between electrons and nuclear spin.

What is difference between fine structure and hyperfine structure?

Fine structure describes the splitting of the spectral lines of atoms due to electron spin and relativistic corrections to the non-relativistic Schrödinger equation. The hyperfine structure is caused by interaction between magnetic field (from electron movement) and nuclear spin.

Is Cesium a word?

cesium in American English a soft, silver-white, ductile, metallic chemical element, one of the alkali metals and the most electropositive of all the elements: it ignites in air, reacts vigorously with water, and is used in photoelectric cells: symbol, Cs; at.

Which is a characteristic of a hyperfine structure?

Any of the spectral lines formed from the splitting of broader spectral lines as a result of the interaction between the magnetic moments of electrons and atomic nuclei is called a Hyperfine structure. And the point at which this happens defines the hyperfine level. UPVOTE.

How are hyperfine states used in quantum computing?

The hyperfine states of a trapped ion are commonly used for storing qubits in ion-trap quantum computing. They have the advantage of having very long lifetimes, experimentally exceeding ~10 min (compared to ~1 s for metastable electronic levels).

Why does hydrogen have a hyperfine energy structure?

But even the so-called ground state of hydrogen is not really a single, definite-energy state, because of the spins of the electron and the proton. These spins are responsible for the “hyperfine structure” in the energy levels, which splits all the energy levels into several nearly equal levels.

What does the second hyperfine level of cesium mean?

What does this mean in layman’s terms: ”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 cesium 133 atom.”?
