We present a new sum rule for Clebsch-Gordan coefficients using generalizedcharacters of irreducible representations of the rotation group. The identityis obtained from an integral involving Gegenbauer ultraspherical polynomials. Asimilar procedure can be applied for other types of integrals of suchpolynomials, and may therefore lead to the derivation of further new relations.
