The effective mass spectrum of two protons from the reaction$p + n \rightarrow pp + \pi^{-}(backward)$ was investigated. The work was carried out at ITEP using a 3-meter magnet spectrometer and a proton beam of 1.98 GeV/c momentum. Liquid deuterium was used as a target. The presented mass spectrum includes about 34000 events. No statistically significant signals from narrow dibaryons were found in the mass region$1.89-2.17\ GeV/c^{2}$ ; the upper limits on narrow dibaryon production cross-section are given. At a mass of$1.8775\ GeV/c^{2}$ a narrow enhancement was found. A more detailed investigation of the observed phenomenon is needed. |
