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.
