The γ-γ angular correlation function for the case where one or both of the γ-ray detectors is able to discriminate between plane polarization states of a γ-ray is given in terms of the corresponding γ-γ directional correlation. The formulas given are directly applicable to one-three type correlations in a triple cascade, and also to direction-plane polarization correlations in which the unpolarized particle is not necessarily a γ-ray, e.g., β-polarized γ. Correlations for the case where the detectors are sensitive to circular polarizations are not treated.
