(Received August 16, 1969)
Current commutation relations and partially conserved axial-vector current hypothesis (PCAC) are applied to the two-photon associated decays of K meson. On the assumption that the effective weak interactions should have the transformation properties discussed by Suzuki in connection with the hadronic decays of kaon, and that the axial-vector isospin charges to which the pions are related through PCAC should be generators of U(2) ×U(2). In the approximation of neglecting the continuation, the decay rates of KL0 →γγand K+ →π+γγ are calculated as a function of the scalar and the pseudoscalar amplitudes, and the pion energy spectrum for the latter decay is obtained.
