vector coupling coefficient

vector coupling coefficient

[′vek·tər ¦kəp·liŋ ‚kō·i‚fish·ənt] (quantum mechanics) One of the coefficients used to express an eigenfunction of the sum of two angular momenta in terms of sums of products of eigenfunctions of the original two angular momenta. Also known as Clebsch-Gordan coefficient; Wigner coefficient.
