+===== Invariant Potential expanded on renormalized spherical Harmonics =====
+###
+Any potential (function) can be written as a sum over spherical harmonics.
+ $V(r,\theta,\phi) = \sum_{k=0}^{\infty} \sum_{m=-k}^{k} A_{k,m}(r) C^{(m)}_k(\theta,\phi)$
+Here  $A_{k,m}(r)$  is a radial function and  $C^{(m)}_k(\theta,\phi)$  a renormalised spherical harmonics.  $C^{(m)}_k(\theta,\phi)=\sqrt{\frac{4\pi}{2k+1}}Y^{(m)}_k(\theta,\phi)$
+The presence of symmetry induces relations between the expansion coefficients such that  $V(r,\theta,\phi)$  is invariant under all symmetry operations. For the C2 Point group with orientation Z the form of the expansion coefficients is:
+###

+==== One particle coupling on a basis of spherical harmonics ====
+###
+The operator representing the potential in second quantisation is given as:
+ $O = \sum_{n'',l'',m'',n',l',m'} \left\langle \psi_{n'',l'',m''}(r,\theta,\phi) \left| V(r,\theta,\phi) \right| \psi_{n',l',m'}(r,\theta,\phi) \right\rangle a^{\dagger}_{n'',l'',m''}a^{\phantom{\dagger}}_{n',l',m'}$
+For the quantisation of the wave-function (physical meaning of the indices n,l,m) we can choose a basis of spherical harmonics times some radial function, i.e.  $\psi_{n,l,m}(r,\theta,\phi)=R_{n,l}(r)Y_{m}^{(l)}(\theta,\phi)$ . With this choice the integral for the expectation value in front of the creation and annihilation operators separates into a radial part and angular part. The angular part has an analytical solution, the radial integral is cast int a parameter.
+ $A_{n''l'',n'l'}(k,m) = \left\langle R_{n'',l''} \left| A_{k,m}(r) \right| R_{n',l'} \right\rangle$
+Note the difference between the function  $A_{k,m}$  and the parameter  $A_{n''l'',n'l'}(k,m)$
+###
+###
+we can express the operator as
+ $O = \sum_{n'',l'',m'',n',l',m',k,m} A_{n''l'',n'l'}(k,m) \left\langle Y_{l''}^{(m'')}(\theta,\phi) \left| C_{k}^{(m)}(\theta,\phi) \right| Y_{l'}^{(m')}(\theta,\phi) \right\rangle a^{\dagger}_{n'',l'',m''}a^{\phantom{\dagger}}_{n',l',m'}$
+###
+###
+The table below shows the expectation value of  $O$  on a basis of spherical harmonics. We suppressed the principle quantum number indices. Note that in principle  $A_{l'',l'}(k,m)$  can be complex. Instead of allowing complex parameters we took  $A_{l'',l'}(k,m) + \mathrm{I}\, B_{l'',l'}(k,m)$  (with both A and B real) as the expansion parameter.

+===== Coupling for a single shell =====

+Although the parameters  $A_{l'',l'}(k,m)$  uniquely define the potential, there is no simple relation between these paramters and the eigenstates of the potential. In this section we replace the parameters  $A_{l'',l'}(k,m)$  by paramters that relate to the eigen energies of the potential acting on or between two shells with angular momentum  $l''$  and  $l'$ .
