Abstract
The and mixing phenomena are reconsidered incorporating new experimental data. Reasonable agreement is obtained in terms of the conventional unitarity, one-photon, and tadpole contributions. No sizable gluonic contributions are required and their presence would tend to destroy the previously achieved agreement. © 1981 The American Physical Society.
