Shell structure of the near-dripline nucleus 23O.

چکیده
Breakup reactions were used to study the ground-state configuration of the neutron-rich isotope 23O. The 22O fragments produced in one-nucleon removal from 23O at 938 MeV/nucleon in a carbon target were detected in coincidence with deexciting gamma rays. The widths of the longitudinal momentum distributions of the 22O fragments and the one-neutron removal cross sections were interpreted in the framework of a simple theoretical model which favors the assignment of Ipi = 1/2+ to the 23O ground state.

Relativistic Hartree-Bogoliubov theory with finite range pairing forces in coordinate space: Neutron halo in light nuclei
The Relativistic Hartree Bogoliubov (RHB) model is applied in the self-consistent mean-field approximation to the description of the neutron halo in the mass region above the s-d shell. Pairing correlations and the coupling to particle continuum states are described by finite range twobody forces. Finite element methods are used in the coordinate space discretization of the coupled system of Di...
متن کاملExploring Neutron-Rich Oxygen Isotopes with MoNA
The Modular Neutron Array (MoNA) was used in conjunction with a large-gap dipole magnet (Sweeper) to measure neutron-unbound states in oxygen isotopes close to the neutron dripline. While no excited states were observed in 24O, a resonance at 45(2) keV above the neutron separation energy was observed in 23O.
متن کاملParticle Unstable Light Nuclei
Exotic nuclei produced in fragmentation reactions can be used to study nuclei beyond the drip lines. The level structure of these nuclei yields information about disappearing, shifting and emerging shells along the driplines. Light nuclei beyond the neutron dripline (for example He, Li, and Be) and the proton dripline (for example N and F) are used to establish the vanishing of the N = 8 and Z ...

The influence of nuclar structure on the r-process nucleosynthesis can best be studied within the ”waiting-point” concept [1]. Within this framework, the successful reproduction of the global isotopic abundances (Nr, ) as well as remaining deficiencies have been interpreted by our group as signatures of nuclear structure near the neutron dripline [1]. Pronounced abundance troughs prior to the N...
متن کاملNuclear Structure and Transfer Reactions of Dripline Nuclei
Systematic studies of isotopic chains including nuclides from the proton to the neutron dripline are an ideal testing ground for nuclear structure theory. Results of Hartree{Fockcalculationsfor oxygen and tin isotopes are discussed. Exploratory calculations for single nucleon transfer reactions on dripline nuclei are presented. In inverse kinematics transfer reactions of ssion fragments the dri...
