Abstract：
the cross section of Ω+Ω→(ΩΩ)_ 0++σ(ε) is studied by using an effective Hamiltonian method. the results show that the scalar meson production cross sections are about 1 to 2 order larger than those of the pseudo–scalar mesons or vector mesons, so the scalar meson production might be an important process for (ΩΩ)_ 0+ production.
