 P: 647 Without further information, all I can say is you find expecation values pretty much the same way you usually do. For example: $$\langle A \rangle = \int_{\sigma} \Psi^{*}\hat{A}\Psi$$ however you will want $\Psi$ to be in spherical coordinates. In other words, you want your solution to Schrodinger's equation to reflect the symmetry of the problem (which I imagine is spherical). For instance if you are working in 3D: $$\langle A \rangle = \int_{\text{Volume}} \psi^{*}(r,\theta,\phi)\hat{A}\psi(r,\theta,\phi)$$ will give you the expectation value of $A$.
