DOIAbstract
International audienceWe report on the proton-induced one-nucleon removal reaction from the neutron-deficient $^{14}$O nucleus with large proton-to-neutron separation energy asymmetry $S_n - S_p$ = 18.6 MeV at 94 MeV/nucleon. The measured inclusive cross sections and parallel momentum distributions (PMDs) of the $^{13}$N and $^{13}$O residues are compared to the state-of-the-art reaction models. It is shown that, in addition to the quasifree knockout, the inelastic scattering and nucleon transfer contribute about 50% and 30% to the proton and neutron removal, respectively. These processes should be considered in analyses of one-nucleon removal cross sections measured at intermediate energies for quantitative nuclear-structure studies
