La g-factor

[mmvdwiel]

lowest level 2D:
2 = 2S+1=> S = 1/2
D level => L = 2
lowest level => J = 3/2
g_J factor is 0.8

Highest level 2D:
S = 1/2, L = 2, J = 5/2
g_J factor is 1.2

We indeed have 5/2=|L+S| >= J >= |L-S|=3/2

When inside lanthanum metal:
The ground state is then 1S0 (source https://www.radiochemistry.org/periodictable/la_series/L8.html), so L = 0, S = 0 and therefore J=0, so gJ = 0 too.
