The g-factor is used in nuclear physics 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 even 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.
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
