Homework Statement
Finding eigenvalues of an hamiltonian
Homework Equations
H = a S²z + b Sz(hbar = 1)
what are the eigenvalues of H in |S,M> = |1,1>,|1,0>,|1,-1>
The Attempt at a Solution
H|1,1> = (a + b) |1,1>H|1,0> = 0
H |1,-1> = (a-b) |1,-1>
which gives directly the energy :
a+b , 0 , a-b
is that right ? Actually I'm not sure about :
S²z |S,M> = M² |S,M>After, I need to calculate the average value of the magnetic moment so I need to be sure of the energy
