Peripheral fragmentation of a 240 MeV/nucleon beam of the halo nucleus 6He incident on carbon target has been studied in a kinematically complete experiment. It is found that one-neutron stripping to the unbound nucleus 5He is the dominant fragmentation mechanism and that it leads to a spin alignment of 5He in a plane perpendicular to the 5He momentum vector. This is expected to be a common feature for all neutron halo nuclei.
