Table of Clebsch–Gordan coefficients
This is a table of Clebsch-Gordan coefficients used for adding angular momentum values in quantum mechanics. The overall sign of the coefficients for each set of constant , , is arbitrary to some degree and has been fixed according to the Condon-Shortley and Wigner sign convention as discussed by Baird and Biedenharn.[1] Tables with the same sign convention may be found in the Particle Data Group's Review of Particle Properties[2] and in online tables.[3]

Formulation
The Clebsch-Gordan coefficients are the solutions to
Explicitly:
The summation is extended over all integral k for which the argument of every factorial is nonnegative.[4]
For brevity, solutions with m < 0 and j1 < j2 are omitted. They may be calculated using the simple relations
- .
and
- .
j2=0
When j2 = 0, the Clebsch-Gordan coefficients are given by .

SU(N) Clebsch-Gordan coefficients
Algorithms to produce Clebsch-Gordan coefficients for higher values of and , or for the su(N) algebra instead of su(2), are known.[5] A web interface for tabulating SU(N) Clebsch-Gordan coefficients is readily available.
