摘要：

A simple derivation of the hard meson result that PCAC and CVC forbid πo, η and vector meson two body, photon decays is given. A model of PCAC breakdown which permits these decays is proposed. The modification PCAC is in agreement with the photon decay data and does not disturb the previous successes of PCAC. © 1968.
