  • ThreeJSymbol[ , , , , , ] gives the values of the Wigner 3-j symbol.
  • The 3-j symbols vanish except when and the 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 .
