The Alt-Grassberger-Sandhas N-body theory is used to study interaction of η mesons with d, 3 He, and 4 He. Separable expansion of the subamplitudes is adopted to convert the integral equations into the quasi-two-body form. The resulting formalism is applied to fit the existing data for low-energy η production of few-nucleon targets. On the basis of this fitting procedure the scattering lengths aηd , aη 3He, aη 4He as well as the subthreshold behavior of the elementary ηN scattering amplitude are obtained.
