D031200100016 FACILITY (SYNCH,2GERGSI) The heavy-ion synchrotron at GSI. D031200100017 The experiments were carried out at the D031200100018 ALADIN-LAND setup. D031200100019 (PRJFS,2GERGSI)The secondary beam of 227 MeV/u 8He D031200100020 and 240 MeV/u 6He was produced in a 8 g/cm2 beryllium D031200100021 production target from a primary beam of 180 with D031200100022 an energy of 340 MeV/u. The 8He or 6He nuclei D031200100023 were separated out from the primary reaction D031200100024 products using the fragment separator FRS. D031200100025 DETECTOR (LONGC) The selected events for the 8He breakup were D031200100026 coincidences between 6He and neutrons, detected in the D031200100027 large area neutron detector, LAND, while alpha-neutron D031200100028 coincidences were selected for 6He.
