The interaction represented by "[this quantity] dot L" gives rise to the "2 J plus 1" degeneracy.
The interaction represented by "[this quantity] dot L" gives rise to the "2 J plus 1" degeneracy. Potts and Ising modeled ferromagnetism using a lattice of variables representing this quantity. It produces a magnetic dipole moment that gives rise to the Zeeman effect. An experiment in which silver atoms were fired through a magnetic field, performed by Stern and Gerlach, showed that this quantity is quantized. Its value is the fourth quantum number, which equals plus or minus one-half for an electron. For 10 points, name this quantity, the intrinsic angular momentum of a subatomic particle.
