Abstract

Coulomb and nuclear breakup of halo nuclei have been studied at RIKEN. In this contribution, we focus on the cases of Coulomb breakup of the one-neutron halo nucleus ¹¹Be at 69MeV/nucleon with a lead target and the nuclear breakup of ¹¹Be at 67MeV/nucleon with a carbon target. In these studies, we have extracted the angular distributions of ¹⁰Be + n c.m. system (inelastic scattering) as well as the relative energy spectra. The angular distributions have been found very important to extract the pure E1 component in the breakup with Pb target, while it has been used to specify the angular momentum of two discrete levels observed for the breakup with C target. We also present preliminary results of Coulomb breakup of the two-neutron halo nucleus ¹¹Li.
