Hyperfine structure — In atomic physics, hyperfine coupling is the weak magnetic interaction between electrons and nuclei. Hyperfine coupling causes the hyperfine splitting of atomic or molecular energy levels. The totality of energy levels spawned by hyperfine… … Wikipedia
Fine structure — Interference fringes, showing fine structure (splitting) of a cooled deuterium source, viewed through a Fabry Pérot étalon. In atomic physics, the fine structure describes the splitting of the spectral lines of atoms due to first order… … Wikipedia
Nucleon spin structure — describes the partonic structure of nucleon (proton and neutron) intrinsic angular momentum (spin). The key question is how nucleon spin 1/2 is carried by its constituents, say partons (quarks and gluons). It was originally expected before the… … Wikipedia
