Condon-Shortley-Wigner phase convention

Condon-Shortley-Wigner phase convention

[¦kän·dən ¦shȯrt·lē ¦wig·nər ′fās kən‚ven·shən]
(quantum mechanics)
Convention relating the phases of states having the same eigenvalue of J 2= Jx 2+ Jy 2+ Jz 2, and different eigenvalues of Jz, whereJis the total angular momentum, according to which the matrix elements ofJ+= Jx + iJy andJ-= Jx-iJy between such states are real.
