Mass spectra measurement in the reaction (p,2p) at protons energy 500 MeV on nuclei C,Al,Cu and Pb

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.
