Skyrme-QRPA calculations for low-lying excitation modes in deformed neutron-rich nuclei
Low-frequency modes of excitation in deformed neutron-rich nuclei are studied by means of the quasiparticle random-phase approximation on the Skyrme-Hartree-Fock-Bogoliubov mean field. We investigate the microscopic structure of the soft Kπ = 0 modes systematically in neutron-rich Magnesium isotopes with N = 22, 24, 26 and 28 close to the drip line, and it is found that the strong collectivity ...
متن کاملLow-lying dipole strength in neutron-rich nuclei
The possibility of performing nowadays reactions with beams of unstable nuclei has opened a new field of study in nuclear physics. Using stable nuclei as targets and carrying out the experiments in inverse kinematics it becomes possible to have access to the excitation spectrum of the incoming short-lived projectiles. To this aim the most often used reactions are the Coulomb excitation and the ...
متن کاملEffective theory for deformed nuclei
Here, I ≥ I0 denotes the angular momentum, A is a constant determined by fit to data, and I0 is the spin of the band head under consideration. Rotational states are the lowestlying excitations in nuclei far away from closed shells. Our understanding of nuclear rotations is based on the groundbreaking work by Bohr and Mottelson [1], its extension within the general collective model [2], and the ...
متن کاملOrigin of low-lying enhanced E1 strength in rare-Earth nuclei.
The experimental E1 strength distribution below 4 MeV in rare-earth nuclei suggests a local breaking of isospin symmetry. In addition to the octupole states, additional J^{π}=1^{-} states with enhanced E1 strength have been observed in rare-earth nuclei by means of (γ,γ') experiments. By reproducing the experimental results, the spdf interacting boson model calculations provide further evidence...
متن کاملQuestion of low-lying intruder states in Be and neighboring nuclei
The presence of not yet detected intruder states in Be, e.g., a J52 intruder at 9 MeV excitation would affect the shape of the b-delayed a spectra of Li and B. In order to test the plausibility of this assumption, shell-model calculations with up to 4\v excitations in Be ~and up to 2\v excitations in Be! were performed. With the above restrictions on the model spaces, the calculations did not y...
