Abstract：
The formation of η-meson-nucleus bound states is investigated,using a standard Green's function of many-body problems.Within physically reasonable range of the parameters (coupling constants and harmonic oscillator potentials),we find that the η-¹⁶O bound state is indeed possible and depends crucially on the ηNN^*(1/2,1－/2) interaction being attractive.Our results indicate that the widths Γ are larger than the η binding energy in ¹⁶O_η,which would make the observation of such states defficult.
