D047300100014 The experiments were carried out at the D047300100015 ALADIN-LAND setup. D047300100016 (PRJFS,2GERGSI)The radioactive 11Li and 14Be beams wereD047300100017 produced in fragmentation reactions of a primary D047300100018 18O beam (325 MeV/u), from the heavy-ion synchrotron D047300100019 at GSI,impinging on an 8 g/cm2 Be target. Separation D047300100020 of the reaction products according to their magnetic D047300100021 rigidity was performed with the fragment separator(FRS)D047300100022 The secondary 11Li beam with an energy of 264 MeV/u, D047300100023 and 14Be beam with an energy of 287 MeV/u, D047300100024 were then transferred to a carbon target (thickness D047300100025 1.29 g/cm2) situated in front of the large-gap D047300100026 magnetic spectrometer ALADIN.
