摘要：
We discuss the possibility to use the recoilless (d,3He) reaction to produce bound states of η and ω mesons in light nuclei. We calculate meson bound states in the nucleus using an optical potential and their formation cross sections with the Green function method, and show that it should be feasible to experimentally observe mesic nuclei in the excitation energy spectrum and to deduce the meson mass shift in nuclei. This method discussed here is complementary to the dilepton invariant-mass spectroscopy, commonly used to study in-medium vector meson masses.
