  Mass spectra of the reaction (p,2p) at the beam energy 500 MeV on nuclei
C,Al,Cu and Pb were measured on two-armed nonmagnetic scintillation
spectrometer (candlepower - 0.2 sr, mass allowance - 4 MeV), which is lokated
on the TRIUMF cyclotron (Canada). Observable anomalies in these spectra can be
stipulated by forming of two-nucleon resonance states.
