Abstract

We present updated and extended results for the η- and η′-nucleus bound state energies, obtained by solving the Schrödinger and Klein-Gordon equations with complex optical potentials, for a wide range of nuclei. The η and η′ nuclear potentials are obtained in the local density approximation from the mass shift of these mesons in nuclear matter, which is calculated within the quark-meson coupling model. Our results show that the η and η′ mesons are expected to form mesic nuclei with all the nuclei considered. However, the signal for the formation of the η- and η′-mesic nuclei may be difficult to identify experimentally due to possible large widths.
