The η-3N interaction is studied within the four-body scattering theory adopting purely separable forms for the two- and three-body subamplitudes, limiting the basic two-body interactions to s waves only. The corresponding separable approximation for the integral kernels is obtained by using the Hilbert-Schmidt procedure. Results are presented for the η-3H scattering amplitude and for the total elastic cross section for energies below the triton break-up threshold.
