the g-factor

We’ve touched upon the g-factor before, as a way to express the magnetic moment of a nucleus. But g-factors are used for objects that are no nuclei too, and in some cases their value can be computed from other properties of the system. In this video, you learn how to express the g-factor of a free electron and a free atom. The latter will be useful when discussing EPR for free atoms.

With this online calculator, it’s a no-brainer to determine the Landé g-factor of a free atom.

Your task for this video: report in the forum underneath the Landé g-factor for each of the following three cases. Mention for every case which information you used as input:

  • the lowest level in the 2D multiplet of the free La atom (see video)
  • the highest level in the 2D multiplet of the free La atom (see video)
  • the ground state of the La atom when it is inside lanthanum metal
