Homework Statement
Find ##\langle L_z \rangle##. What is ##\langle L_Z \rangle## for one atom only?
Homework Equations
The Attempt at a Solution
Using ##L_z = -i\hbar \frac{\partial }{\partial \phi}##,
I get:
[tex]\langle L_z\rangle = \frac{32}{3} \pi k^2 \hbar a_0^3[/tex]
Not sure what the significance of this is. That it is non-zero? All the atoms somehow interact and produce a net angular momentum about z.
For a single atom I think it is zero.
