Abstract：
The formation of the bound state of the η-mesic-aucleus is investigated by the standard Green's function method used in the many-body problem. It is found that when parameters, coupling constants and harmonic oscillator potentials are chosen in the physical range, due to the attractive nature of the ηNN ^*(l/2, 1/2 ^-) interaction the η- ¹⁶O bound state can possibly be formed. However, detecting such a bound state would be difficult, because its width Γ is larger than the binding energy of ηin ¹⁶O _η.
