ClebschGordan[{j1, m1}, {j2, m2}, {j, m}]
gives the Clebsch-Gordan coefficient for the decomposition of ❘j,m〉 in terms of ❘j_1,m_1〉❘j_2,m_2〉.
  • The Clebsch-Gordan coefficients vanish except when m=m_1+m_2 and the j_i 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.
