AbstractDissociation of a 227 MeV/u He-8 beam in a lead target has been studied in a kinematically complete experiment. The results are compared with similar data from the well-known halo nucleus He-6. Coulomb-nuclear interference in the inelastic channel gives evidence for a I-π = 1- resonance in He-8 at E-x = 4.15 MeV. The deduced B(E1) value of 0.38 ± 0.07 e(2) fm(2) indicates a uniform distribution of the four neutrons around the α-particle core.
