ClebschGordan[{j1, m1}, {j2, m2}, {j, m}]
gives the Clebsch-Gordan coefficient for the decomposition of in terms of .


  • The Clebsch-Gordan coefficients vanish except when and the satisfy a triangle inequality.
  • The parameters of ClebschGordan can be integers, half-integers, or symbolic expressions.
  • Mathematica uses the standard conventions of Edmonds for the phase of the Clebsch-Gordan coefficients.
