Abstract：
A two-step process for forming dibaryon (ΩΩ)0+ is studied. The first step is N+Ω→(NΩ)₀₂₂+γ, or N+Ω→(NΩ)₀₂₂+π,and the second step is an exchange reaction as:Ω+(NΩ)₀₂₂→(ΩΩ)₀₀₀+N. The results show that the cross sections of both steps are quite large,therefore this might be an important approach for producing (ΩΩ)0+.
