sup 8 He- sup 6 He: a comparative study of electromagnetic fragmentation reactions
Dissociation of a 227 MeV/u sup 8 He 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 sup 6 He. Coulomb-nuclear interference in the inelastic channel gives evidence for a I suppi=1 sup - resonan...

description | Dissociation of a 227 MeV/u sup 8 He 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 sup 6 He. Coulomb-nuclear interference in the inelastic channel gives evidence for a I suppi=1 sup - resonance in sup 8 He at E sub x =4.15 MeV. The deduced B(E1) value of 0.38+-0.07 e sup 2 fm sup 2 indicates a uniform distribution of the four neutrons around the alpha-particle core. |
