Nuclear structure studies using high-energy radioactive nuclear beams

Recent experimental results using beams of radioactive nuclei are reviewed. Radioactive beams produced through projectile fragmentations of high-energy heavy ions have been used for measurements of interaction and fragmentation cross sections. From the measured interaction cross sections, radii of unstable nuclei were deduced for light p-shell nuclei. The isospin dependence as well as the isotope dependence of the nuclear radii are discussed. The projectile fragmentation of exotic nuclei, 11Li, have recently been observed. The existence of neutron halo in 11Li nuclei is suggested from the data. The possibility of studying the space and the momentum distributions of nucleons in exotic nuclei are also discussed. (orig.)
