Abstract
Peripheral fragmentation of a 240 MeV/nucleon beam of the halo nucleus He-6 incident on carbon target has been studied in a kinematically co mplete experiment. It is found that one-neutron stripping to the unbou nd nucleus He-5 is the dominant fragmentation mechanism and that it le ads to a spin alignment of He-5 in a plane perpendicular to the He-5 m omentum vector. This is expected to be a common feature for all neutro n halo nuclei.
