Large-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 کاملp–SHELL NUCLEI AND TWO-FREQUENCY SHELL MODEL WITH A REALISTIC EFFECTIVE INTERACTION
We have studied p-shell nuclei using a two-frequency shell-model approach with an effective interaction derived from the Bonn-A nucleon-nucleon potential by means of a G-matrix folded-diagram method. First, we briefly describe our derivation of the effective interaction in a model space composed of harmonic oscillator wave functions with two different length parameters, bin and bout, for the co...
متن کاملLarge-space shell-model calculations for light nuclei.
An effective two-body interaction is constructed from a new Reidlike NN potential for a large no-core space consisting of six major shells and is used to generate the shell-model properties for light nuclei from A=2 to 6. For practical reasons, the model space is partially truncated for A=6. Binding energies and other physical observables are calculated and they compare favorably with experimen...
متن کاملAb initio no-core shell model calculations for light nuclei
— An overview of the ab initio no-core shell model is presented. Recent results for light nuclei obtained with the chiral two-nucleon and three-nucleon interactions are highlighted. Cross section calculations of capture reactions important for astrophysics are discussed. The extension of the ab initio no-core shell model to the description of nuclear reactions by the resonating group method tec...
متن کاملComment on "Large-space shell-model calculations for light nuclei"
In a recent publication Zheng, Vary, and Barrett reproduced the negative quadrupole moment of Li and the low-lying positive-parity states of He by using a no-core shell model. In this Comment we question the meaning of these results by pointing out that the model used is inadequate for the reproduction of these properties.
