When there are two particles with spin s(adsbygoogle = window.adsbygoogle || []).push({}); _{1}and s_{2}the composite system has possible spins s_{1}+s_{2}all the way down to |s_{2}-s_{1}| (using integer steps). The azimuthal quantum number goes from s_{1}+s_{2}to -s_{1}+s_{2}(using integer steps).

Now my question is if we had three particles (or more) how would we calculate their possible composite spin?
