Gamow shell model description of neutron-rich nuclei.
This work presents the first continuum shell-model study of weakly bound neutron-rich nuclei involving multiconfiguration mixing. For the single-particle basis, the complex-energy Berggren ensemble representing the bound single-particle states, narrow resonances, and the nonresonant continuum background is taken. Our shell-model Hamiltonian consists of a one-body finite potential and a zero-ran...
متن کاملEffective interaction techniques for the Gamow shell model
We apply a contour deformation technique in momentum space to the newly developed Gamow shell model, using the drip-line nuclei 5He, 6He, and 7He as test cases. A major problem in Gamow shell-model studies of nuclear many-body systems is the increasing number of many-body configurations due to the large number of resonant and complex-continuum single-particle orbits necessary to reproduce multi...

متن کاملLarge-basis shell-model calculations for p-shell nuclei
Results of large-basis shell-model calculations for nuclei with A = 7 − 11 are presented. The effective interactions used in the study were derived microscopically from the Reid93 potential and take into account the Coulomb potential as well as the charge dependence of T = 1 partial waves. For A = 7, a 6h̄Ω model space was used, while for the rest of the studied nuclides, the calculations were p...
متن کاملEffective interaction for pf-shell nuclei
An effective interaction is derived for use in the full p f basis. Starting from a realistic G-matrix interaction, 195 two-body matrix elements and four single-particle energies are determined by fitting to 699 energy data in the mass range 47–66. The derived interaction successfully describes various structures of p f -shell nuclei. As examples, systematics of the energies of the first 2 state...
