| Abstract | |
We present updated and extended results for the eta- and eta' -nucleus bound state energies, obtained by solving the Schrodinger and Klein-Gordon equations with complex optical potentials, for a wide range of nuclei. The eta and eta' 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 eta and eta' mesons are expected to form mesic nuclei with all the nuclei considered. However, the signal for the formation of the eta- and eta'-mesic nuclei may be difficult to identify experimentally due to possible large widths. (AU) | |
