  "abstract": "The usefulness of the three-body mechanism of $\\eta$-meson production is tested by extending to high energies a recently developed two step model of the $p d \\to ^3$He $\\eta$ reaction by us, which was successful in reproducing the energy dependence of the data near threshold. The $\\eta$ production in this model, proceeds in two steps via the $p p \\to \\pi d$ and $\\pi N \\to \\eta p$ reactions with the intermediate particles being off-shell. The final state interaction(FSI) is incorporated through a $T$-matrix for $\\eta^3$He elastic scattering constructed using few body equations. In a comparison of the calculated angular distributions with some recently available data, we discover the limitations of the model at high energies.",
