Consider the Dirac equation for bounded electron in hydrogen atom. I am trying to get a clear physical explanation for all mathematical terms that appear in the Hamiltonian and energy spectrum. The hyperfine structure in atomic spectra has been discussed in Sec. 4.6. There we showed that an s -wave electronic state interacts with the nuclear spin through the Fermi contact term, whereas orbitals with l ≠ 0 interact via a 1 ∕ r 3 dipole–dipole interaction.

Hyperfine structure doubles all the energy levels. In the ground state the In the ground state the F=0-F=1 splitting is 1420 MHz, which corresponds to a wavelength of 21 cm. The consequences of zero field quantum beat studies in electron impact to the measurement of scattering parameters in electron sodium collision is explored. The beats in sodium, which were first observed in an electron photon coincidence experiment, arise from the decay of coherently excited hyperfine levels in the J=3/2 level of the 32P state.

Hyperfine Structure The proton in a hydrogen atom is a spin one-half charged particle, and therefore possesses a magnetic moment. By analogy with Eq. , we can write (1004) where is the proton magnetic moment, is the proton spin, and the proton gyromagnetic ratio is found experimentally to take that value .

As experiments became more precise, more energy levels were found, requiring the concept of electron spin and the Atomic Spectroscopy provides a comprehensive discussion on the general approach to the theory of atomic spectra, based on the use of the Lagrangian canonical formalism. This approach is developed and applied to explain the hydrogenic hyperfine structure associated with the nucleus motion, its

hyperfine structure of an atom with an S-state is given by FEIr (3) as where I is the nuclear spin, #o is the Bohr magneton, # is the nuclear moment and ~o2(0) is the square of the wave function for the valence electron at the electron, and, consequently, the hyperfine structure smaller than the fine structure. We use the PAULI approximation, so that k2 is a constant of the motion and I is a good quantum number.

When there is no magnetic field, we get just one spectral line from the hyperfine structure of hydrogen. The transitions between state $\ketsl{\slIV}$ and any one of the others occurs with the absorption or emission of a photon whose frequency $1420$ megacycles is $1/h$ times the energy difference $4A$. When the atom is in a magnetic field $\FLPB$, however, there are many more … Hyperfine structure, with energy shifts typically orders of magnitudes smaller than those of a fine-structure shift, results from the interactions of the nucleus (or nuclei, in molecules) with internally generated electric and magnetic fields.
