(\Omega \Omega)_{0^+} dibaryon productions in central Au+Au collisions   at RHIC energy \sqrt {s_{NN}} =130GeV
  Based on the measured transverse mass spectra of \pi^-, K^- and \bar p at the RHIC energy \sqrt {s_{NN}} =130GeV, di-omega productions from baryon-baryon reactions in hadronic matter are studied. Results about the (\Omega \Omega)_{0^+} total number per event show that the deeply bound state (\Omega \Omega)_{0^+} can be observed at RHIC energies.
