    • The spherical tensors τ QK are homogeneous polynomials of order K constructed from the angular momentum operators J as τ QK = NKJ (J) K YKQ (x,y,z), where YKQ (x,y,z) = rK YKQ (θ) are the solid harmonic functions. The choice of normalization factor NKJ = 2K K! 4π (2J-K) ! (2J+1) (2J+K+1) ! leads to their matrix elements in the { | JM } basis as given in the text. Note that the operators τ QK are related to the T KQ of Ref. through τ QK = [J] T KQ, so that τ 00 is a (2J+1) × (2J+1) identity matrix.
