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 η in ¹⁶O_η.
