    "abstract": "We propose to use the recoilless (d,$^3$He) reaction to produce $\\eta$-mesic\nnuclei. This reaction has been used to observe deeply bound pionic states and\nproven to be powerful recently. We calculate $\\eta$-mesic bound states in the\nnucleus using an optical potential and their formation cross section with the\nGreen function method. Then, we carefully check the experimental feasibility.\nWe find that $\\eta$-mesic nuclei can be observed experimentally using the\n(d,$^3$He) reaction. We also mention the possibility to study the formation of\n$\\omega$-mesic nuclei.",
