Abstract
The effective mass spectra of two nucleons from the reactionpd →ppn were studied at four incident proton energies in the range 800–1000 MeV, one of nucleons being backward emitted. After selecting the events either with large nucleon momenta or with large opening angles between the nucleons several narrow peaks are observed in the effective mass spectra (M=1.95, 2.03, 2.08 and 2.14 GeV/c2) which can be considered as probable dibaryon resonances.
