In the framework of the unitary symmetry scheme, the stabilities of the irreducible representations of the baryon-boson systems are considered for both cases of the symmetry limit and of the broken symmetry, using the static approximation. The one dimensional and ten dimensional representations seem to be most stable, and the levels of them are identified with the resonant levels of Y_0^*, N_<3/2>^*, Y_1^* and Ξ_<1/2>^*, by adjusting the parameters α,β and A which are the mixing parameters between the D coupling interaction and the F coupling interaction and cut-off energy, respectively. The mass of the I=0 member of the ten dimensional multiplets is predicted. Furthermore, the coupling constants among baryons and bosons and the possibility of explaining the small branching ratio of Y_1^* are obtained from these parameters.
