Homework Statement
Consider two identical particles of mass m and spin 1/2. They interact via a potential given by
[tex]V=\frac{g}{r}\hat{\sigma}_1\cdot\hat{\sigma}_2[/tex]
where g>0 and [tex]\hat{sigma}_j[/tex] are Pauli spin matrices which operate on the spin of particle j.
a) Construct the spin eigenfunctions for the two particle states. What is the expectation value of V for each of these states?
b) Give eigenvalues of all the bound states
Homework Equations
The Attempt at a Solution
I'm really not sure where to start. I'm used to the Hamiltonian taking the form
[tex]H=\frac{\hat{p}^2}{2m}+V[/tex]
but I don't see how I can apply that at all. Is this easier than I'm making it?
I thought I was relatively good at Q.M... hints?
