let us denote the joint eigenstate of [itex]\hat{L^{2}}[/itex]and [itex]\hat{L_{z}}[/itex] by ll,m> and we know that if we are in spherical coordinates,(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\hat{L^{2}}[/itex] and [itex]\hat{L_{z}}[/itex] depend on θ and ∅, so we denote the joint eigenstate by: <θ∅l l,m>.. why?
