Olimov K.K., Lutpullaev S.L., Lugovoi V.V., et al. Breakup of oxygen nucleus on isotopes of hydrogen and nitrogen nuclei in collisions with protons at 3.25AGeV/c.

Phenomenological analysis of breakup of oxygen nuclei on fragments with the charges one and seven in collisions with protons at 3.25AGeV/c was conducted using the Monte Carlo model of isotropic phase space. For the first time, the contributions of mechanism of diffractive breakup of oxygen nucleus and that of quasi-elastic knocking out of one of the protons of oxygen nucleus by a proton target into channel of formation of proton fragment and 15N nucleus with conservation of recoil proton in final state were determined. Cross-section of diffractive breakup of oxygen 16O nucleus on 15N nucleus and proton fragment and that of diffractive breakup of 16O nucleus on nuclei 14Nand 2H were estimated for the first time in 16Op collisions at 3.25AGeV/c.
