The cross section for pion-pair production by two photons is calculated approximately by using the low energy theorem previously derived from the partially-conserved-axial-vector-current hypothesis and current algebra and found to agree very well with the experimental data recently obtained by the Mark II, TPC/Two-Gamma, and CLEO Collaborations.
