Homework Statement
Find the generators of the four dimensional irreducible representation of SO(3), such that J_3 is diagonal.
The Attempt at a Solution
I know how to get the rest if I know J_3, by using ladder operators. But what is J_3?
For a 3d representation it's diagonal with 1,0-1, in 4d would it be 3/2, 1/2, -1/2 -3/2? Wasn't orbital angular momentum supposed to be of integer values, or did I forget QM so bad?
Thanks for any help

nevermind, it is obviously not necessarily orbital angular momentum so that works..
