    "abstract": "The scattering lengths of eta-meson collisions with light nuclei d,t,3He, and\n4He are calculated on the basis of few-body equations in coherent\napproximation. It is found that the eta-nucleus scattering length depends\nstrongly on the number of nucleons and the potential-range parameter. By taking\ninto account the off-shell behavior of the eta-N amplitude, the eta-4He\nscattering length increases considerably.",
