Phenomenological analysis of breakup of oxygen nuclei on fragments with charges two and six in collisions with protons at 3.25A GeV/c was conducted using the Monte Carlo (MC) 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 α clusters of oxygen nucleus by a proton target, into channel of formation of α particle and 12C nucleus with conservation of recoil proton were determined in final state. The substantial role of α cluster structure of initial nucleus in processes of fragmentation of oxygen nuclei in peripheral interactions with protons was revealed in experiment.
