ThreeJSymbol[{j1, m1}, {j2, m2}, {j3, m3}]
gives the values of the Wigner 3-j symbol.
  • The 3-j symbols vanish except when m_1+m_2+m_3=0 and the j_i satisfy a triangle inequality.
  • The parameters of ThreeJSymbol can be integers, half-integers or symbolic expressions.
  • The Clebsch-Gordan coefficients and 3-j symbols in Mathematica satisfy the relation .
