Abstract

Within the framework of isobaric models of pseudoscalar meson photoproduction, the nonresonant background of photoproduction of η-mesons on nucleons is investigated as a function of energy. A bound on the magnitude of the pseudoscalar coupling constant of the η-meson with a nucleon is obtained: gηNN 2/4π ≤ 0.01, and a bound on vector meson exchange models is also obtained.
