Probing shell structure and shape changes in neutron-rich sulfur isotopes through transient-field g-factor measurements on fast radioactive beams of 38S and 40S.

چکیده
The shell structure underlying shape changes in neutron-rich nuclei near N = 28 has been investigated by a novel application of the transient-field technique to measure the first-excited-state g factors in 38S and 40S produced as fast radioactive beams. There is a fine balance between proton and neutron contributions to the magnetic moments in both nuclei. The g factor of deformed 40S does not resemble that of a conventional collective nucleus because spin contributions are more important than usual.

Neutron capture measurements at a RIA - type facility
Neutron capture cross sections of unstable isotopes are important for neutron induced nucleosynthesis as well as for technological applications. The Rare Isotope Accelerator (RIA) or comparable facilities will be able to produce radioactive ion beams up to 10 12 particles/s and would therefore be a suitable place for (n,γ) studies on radioactive isotopes with half-lives between days and months....
متن کاملProposal for the 252 Cf source upgrade to the ATLAS facility
Beams of accelerated exotic neutron-rich nuclei allow access to little known regions of the nuclear landscape that are important both structurally and for r-process nucleosynthesis. We propose to increase the radioactive beam capabilities of the ATLAS accelerator facility by the installation of a new source of ions to provide beams of shortlived neutron-rich isotopes. These isotopes will be obt...
متن کاملFolding model analysis of elastic and inelastic proton scattering on Sulfur isotopes
The folding formalism for the nucleon-nucleus optical potential and inelastic form factor is applied to study elastic and inelastic proton scattering on 30−40S isotopes. A recently developed realistic density dependent M3Y interaction, well tested in the folding analysis of nucleus-nucleus elastic and inelastic scattering, is used as effective NN interaction. The nuclear ground state and transi...

The new ReA3 re-accelerated beam facility at the National Superconducting Cyclotron Laboratory (NSCL) will provide high quality radioactive ion beams (RIBs), produced from fast fragmentation reactions, at energies around the Coulomb barrier. These radioactive isotopes can have exotic properties such as neutron/proton skins, halos, or unexpected changes in their shell structure. ReA3 will allow ...
متن کاملProbing the high-density behavior of nuclear symmetry energy with high-energy radioactive beams
Central collisions induced by high energy radioactive beams can be used as a novel means to obtain crucial information about the high density (HD) behaviour of nuclear symmetry energy. This information is critical for understanding several key issues in astrophysics. Within an isospin-dependent hadronic transport model using phenomenological equations of state (EOS) for dense neutron-rich matte...
