Enumeration of States and the Multiplicity Function
(Let us assume N even) N? : number of up spins, N?: number of down spins
Multiplicity function g(N,s) of a state with a given spin excess
Ex. Form of g(10,s) as a function of 2s:
Binary alloy systems: (N-t) A atoms and (t) B atoms on N sitesthe same multiplicity function
