ground state of these three ions with Hund's rule. (b) Assume
the same ion density n=N/V, compare the susceptibility of a 
compound
to that of 
at the same temperature.
(c) Assume the same ion density n=N/V, compare the susceptibility
of a 
compound to that of 
at
the same temperature. The g-factor is given by the Lande equation:
