摘要：

The pseudoscalar and pseudovector eta N coupling constants are calculated from an effective vertex associated with the alpha(0)(980)pi N triangle diagram. The predicted values are in agreement with the ones concluded from fitting eta photoproduction amplitudes. In this context we stress the importance of the properties of the scalar meson octet for eta meson physics.
