Radiative proton capture on 6He

Radiative capture of protons is investigated as a probe of clustering in nuclei far from stability. The first such measurement on a halo nucleus is reported here for the reaction He-6(p, gamma) at 40 MeV. Capture into Li-7 is observed as the strongest channel. In addition, events have been recorded that may be described by quasifree capture on a halo neutron, the alpha core, and He-5. The possibility of describing such events by capture into the continuum of Li-7 is also discussed.
