Breakup of oxygen nucleus on isotopes of hydrogen and nitrogen nuclei in collisions with protons at 3.25A GeV/c

Abstract

Phenomenological analysis of breakup of oxygen nuclei on fragments with the charges one and seven in collisions with protons at 3.25[Formula: see text][Formula: see text]GeV/[Formula: see text] 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 [Formula: see text]N nucleus with conservation of recoil proton in final state were determined. Cross-section of diffractive breakup of oxygen [Formula: see text]O nucleus on [Formula: see text]N nucleus and proton fragment and that of diffractive breakup of [Formula: see text]O nucleus on nuclei [Formula: see text]N and 2H were estimated for the first time in [Formula: see text]O[Formula: see text] collisions at 3.25[Formula: see text][Formula: see text]GeV/[Formula: see text].
