Hello all! (I'm new to the forum)(adsbygoogle = window.adsbygoogle || []).push({});

I'd like to ask if you could give me a simple explanation regarding the 6j symbols: I don't understand their formulation in terms of Clebsch-Gordan coefficients with three angular momenta and the related "tetrahedron rule".

Alternatively, could you please suggest me a book to consult?

Thank you very much for your help!
