Experimental studies using an energetic beam of 8He and 14Be

This contribution concerned an experiment, that has been performed to study properties of halo nuclei in reaction studies at several 100 MeV/nucleon. At GSI (Darmstadt, Germany), halo nuclei are studied in neutron break-up reactions. All momenta of the fragments emerging from the reaction zone are reconstructed in kinematically complete measurements. Present work is dedicated to analysis of quasi-free scattering of relativistic 8He and 14Be beams on hydrogen target. In addition to neutron and fragment momentum distributions, the detection of recoiled protons in coincidence provides additional information. This gives access to the internal correlations of the studied nuclei and allows for a reconstruction of the momentum transfer in the reaction in inverse kinematics. First results and the underlying analysis steps will be presented in my poster. (orig.)
