This work presents one of the several experiments at the R3B-LAND setup (at GSI in Darmstadt, Germany), dedicated to investigations of nuclear structure with proton-induced quasi-free scattering reactions in inverse kinematics at relativistic energies. Kinematically complete measurements were undertaken, which allow for the analysis of (p,2p) and (p,pn) reactions. A similar technique with an upgraded setup will be used for the future R3B program at FAIR/GSI, for studies of the single-particle structure and the role of N-N correlations in very exotic nuclei. One-neutron (p,pn) and one-proton (p,2p) quasi-free knockout reactions on the 57Ni nucleus are being analyzed within this work. Position, time-of-flight and energy-loss measurements of heavy ions and light particles before and after the target were undertaken. A clean identification of the quasi-free scattering reactions on a proton target can be achieved with the detector system around the target area, in combination with the exclusive identification of the reaction participants.
