Double_Helix
A fictitious system having three degenerate angular momentum states with ##\ell=1## is described by the Hamiltonian \hat H=\alpha (\hat L^2_++\hat L^2_-) where ##\alpha## is some positive constant. How to find the energy eigenvalues of ##\hat H##?

How would you usually find the eigenvalues of an operator?

Also, the end tag is [/tex], not [\tex]. Or you can just use double hashes (##) for both tags instead.

    I tried to write the matrix form of the operator.

And that looked like? What did you do after that?
