    "abstract": "It is shown that the striking energy variation in the $p\\, d \\rightarrow\n\\mbox{$^{\\, 3}{\\rm He}$}\\, \\eta$ cross section near threshold is probably due\nto a final state interaction associated with a large (complex) $\\eta\n-\\mbox{$^{3}{\\rm He}$}$ scattering length. The consequences of this hypothesis\nare studied for the production of the meson in the $\\eta -\\mbox{$^{4}{\\rm\nHe}$}$ and $\\eta -\\mbox{$^{7}{\\rm Be}$}$ channels.",
