Single-particle properties of drip line nuclei can be investigated via tran
sfer reactions induced by-intense secondary beams. The Be-11(p,d) and Be-11
(d,He-3) one-nucleon pick-up reactions have been studied in inverse kinemat
ics. The goal was to provide a test of the various competing models for the
structure of halo nuclei Be-11 and Li-11.
