Fermi contact interaction
The Fermi contact interaction is the magnetic interaction between an electron and an atomic nucleus. Its major manifestation is in electron paramagnetic resonance and nuclear magnetic resonance spectroscopies, where it is responsible for the appearance of isotropic hyperfine coupling. This … See more Roughly, the magnitude of A indicates the extent to which the unpaired spin resides on the nucleus. Thus, knowledge of the A values allows one to map the singly occupied molecular orbital. See more The interaction was first derived by Enrico Fermi in 1930. A classical derivation of this term is contained in "Classical Electrodynamics" by See more WebLooking for Fermi interaction? Find out information about Fermi interaction.

The isomer shift is directly proportional to nabs( R )-nsrc( R ), the difference in electron density at the absorber (sample) and the source.
WebSimple Derivation of the Electron-Nucleus Contact Hyperfine Interaction Full Record Related Research Abstract A derivation is given of the Fermi formula for the contact hyperfine interaction energy between the magnetic moment of a nucleus and that of the surrounding electrons.
WebA model for the Fermi contact interaction is proposed in which the nuclear moment is represented as a magnetized spherical shell of radius ro. For a hydro- gen-like system thus perturbed, the Schr6dinger equation is solvable without perturbation theory by use of the Coulomb Green's function. ...
