Shell structure of exotic nuclei

Particle-vibration coupling and shell structure of exotic nuclei

We discuss the effects of particle-vibration coupling on the shell structure of nuclei near the neutron drip line by choosing, as examples, 10Be and 24O cores. In particular, we calculate the energy shifts of single-particle neutron states induced by the interaction with collective modes. In the case of the 10Be core, the coupling to 2+ states is responsible, within our model, of narrowing the ...

Shell Closures in Exotic Nuclei

Inspired by the recent experiments [1]-[3] indicating unusual doubly magic nucleus O which lies just at the neutron drip-line and encouraged by the success of our relativistic mean-field (RMF) plus state dependent BCS approach for the description of the ground state properties of the drip-line nuclei [23]-[27], we have further employed this approach, across the entire periodic table, to explore...

Structure and Reactions of Exotic 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{Fock calculations for magnesium and tin isotopes are discussed. Ground states and the multipole response of superheavy nuclei are investigated with HF and RPA calculations. Exploratory calculations for single nucleon transf...

Clusters and Shell-Structure in Light Nuclei

Thomas Neff, Hans Feldmeier and Robert Roth Gesellschaft für Schwerionenforschung mbH, Planckstraße 1, 64291 Darmstadt, Germany †Institut für Kernphysik, TU Darmstadt, Schlossgartenstraße 9, 64289 Darmstadt, Germany Abstract. Light nuclei in the p-shell are studied in the Fermionic Molecular Dynamics model. No a priori assumptions are made with respect to cluster structure or single-particle en...
