In physics, the Clebsch–Gordan (CG) coefficients are numbers that arise in angular momentum coupling in quantum mechanics. They appear as the expansion coefficients of total angular momentum eigenstates in an uncoupled tensor product basis. In more mathematical terms, the CG coefficients are used in … See more Angular momentum operators are self-adjoint operators jx, jy, and jz that satisfy the commutation relations By developing this concept further, one can define another operator j as the inner product of … See more The recursion relations were discovered by physicist Giulio Racah from the Hebrew University of Jerusalem in 1941. Applying the total angular momentum raising and lowering operators (and is therefore … See more For J = 0 the Clebsch–Gordan coefficients are given by For J = j1 + j2 and M = J we have For j1 = j2 = J / 2 and m1 = −m2 we have For j1 = j2 = m1 = −m2 we have For j2 = 1, m2 = 0 we have For j2 = 1/2 we have See more It can be shown from the above definitions that j commutes with jx, jy, and jz: When two Hermitian operators commute, a common set of eigenstates exists. Conventionally, j … See more We now consider systems with two physically different angular momenta j1 and j2. Examples include the spin and the orbital angular momentum of a single electron, or the … See more These are most clearly written down by introducing the alternative notation The first orthogonality relation is See more A convenient way to derive these relations is by converting the Clebsch–Gordan coefficients to Wigner 3-j symbols using 3.
