Abstract
The two-photon decays of the pseudoscalar mesons are studied in terms of the fundamental quark-antiquark annihilation amplitude. The similarity of the pseudoscalars to parapositronium is stressed. In particular, it is shown that the atomic physics result for the decay width of parapositronium, modified in certain cases to accommodate strong-binding effects, is applicable to these hadrons and leads to values for their two-photon widths which are in accord with experimental results.Keywords
