Wigner's 3-j symbols, also called 3-jm symbols, are used in quantum mechanics as an alternative to Clebsch–Gordan coefficients for adding angular momenta.
Notes on verification
Confirmed by multiple independent technical sources (MathWorld, arXiv papers, Semantic Scholar) consistent with standard quantum mechanics literature. [tier=gold indep_score=0.867 clusters=3 claim_tier=everyday]
