摘要：

Dibaryons which have a very narrow decay width, called super-narrow dibaryons, are searched for by the p+d scattering at E-p = 295 MeV. The experiment was carried out at the Research Center for Nuclear Physics employing a two-arm magnetic spectrometer. A good mass resolution of 0.95 MeV and background free condition have been achieved. No resonance has been observed in the mass region of 1896-1914 MeV. The upper limits of the dibaryon production cross section have been determined.
