Thanks for getting back to me. I understand conceptually why the expectation value of L+ is equal to zero. I guess I'm more asking what the proof is for that. Obviously since it is just an operator it will have a zero likelihood of being anywhere, but I just don't know why in this equation my...
This might be a basic question, but I'm having some difficulty understanding expectation values and ladder operators for angular momentum.
<L+> = ?
I know that L+ = Lx+iLy, but I don't know what the expectation value would be?
Someone told me something that looked like this...
In order to get the probabilities you need to use the Clebsch-Gordan table.
From the original equation we know that Y01 is the same as |10> and Y11 is the same as |11>. We also know that electrons have an inherent spin of 1/2, so the chi (+) is |1/2 1/2> and the chi (-) is |1/2 -1/2>.

Hi,
You cannot use infinity, because the problem states that there is an infinite length of wire. This tells us that the charge is infinite. Using a variable like "a" is your best bet for solving the problem.
