  • Interaction cross sections for Ne isotopes towards the island of inversion and halo structures of 29Ne and 31Ne

    • Interaction cross sections (σI) for Ne isotopes from the stability line to the vicinity of the neutron dripline have been measured at around 240 MeV/nucleon using BigRIPS at RIBF, RIKEN. The σI for 27–32Ne in every case exceed the systematic mass-number dependence of σI for stable nuclei, which can be explained by considering the nuclear deformation. In particular the σI for 29Ne and 31Ne are significantly greater than those of their neighboring nuclides. These enhancements of σI for 29Ne and 31Ne cannot be explained by a single-particle model calculation under the assumption that the valence neutron of 29Ne (31Ne) occupies the 0d3/2 (0f7/2 ) orbital, as expected from the standard spherical shell ordering. The present data suggest an s dominant halo structure of 29Ne and s- or p-orbital halo in 31Ne.

  • Structure of 8Li from a reaction cross-section measurement
  • 2014
  • Ingår i: Phys. Rev. C. - American Physical Society. ; 90, s. 044321-
  • Tidskriftsartikel (refereegranskat)abstract
    • We have precisely measured reaction cross sections (σR) for 8Li using 9Be, 12C, 27Al, and proton targets at intermediate energies by the transmission method. From the energy dependence of the σR including the high energy data, the density distribution of 8Li was deduced through a modified Glauber model. It is shown that 8Li has a shorter tail structure in the density as compared with that of 8B and the matter radius of 8Li is similar to those of the other nonhalo Li isotopes. The result is consistent with the previous experiments that there is a tendency for 8Li to be a skin nucleus.

  • Energy-dependent charge-changing cross sections and proton distribution of 28Si
  • 2010
  • Ingår i: Phys. Rev. C. ; 82, s. 014609-1-014609-6
  • Tidskriftsartikel (refereegranskat)abstract
    • The charge-changing cross sections (σcc) of 28Si on a carbon target were measured with high precision atintermediate energies from 100 to 600 MeV/nucleon. The measured σcc decreases rapidly from low energies upto 200 MeV/nucleon, whereas at higher energies it appears almost constant. The energy dependence of σcc iscompared with a Glauber-type model calculation where only the proton distribution of 28Si is taken into account.A phenomenological correction factor deduced from the present data satisfactorily reproduces the experimentalσcc for other stable nuclei, whose charge distributions were determined by electron scattering and muon captureexperiments.
