    "abstract": "The pseudoscalar and pseudovector $\\eta N$ coupling constants are calculated\nfrom an effective vertex associated with the $a_0(980)\\pi N$ triangle diagram.\nThe predicted values are in agreement with the ones concluded from fitting\n$\\eta $ photoproduction amplitudes. In this context we stress the importance of\nthe properties of the scalar meson octet for $\\eta $ meson physics.",
