چکیده

Large-space no-core shell model calculations have been performed for 3H, 4He, 5He, 6Li, and 6He, using a starting-energy-independent two-body effective interaction derived by application of the Lee-Suzuki similarity transformation. This transformation can be performed by direct calculation or by different iteration procedures, which are described. A possible way of reducing the auxiliary potential influence on the two-body effective interaction has also been introduced. The many-body effects have been partially taken into account by employing the recently introduced multi-valued effective interaction approach. Dependence of the 5He energy levels on the harmonic-oscillator frequency as well as on the size of the model space has been studied. The Reid 93 nucleon-nucleon potential has been used in the study, but results have also been obtained using the Nijmegen II potential for comparison.

Large-basis shell model studies of light nuclei with a multivalued G-matrix effective interaction.

Large-basis shell model studies of low-lying excitations in light nuclei from He to Li have been performed with a multivalued G-matrix effective interaction, as recently suggested by Haxton et al.. Calculations were performed relative to the vacuum (“no core”) using very large, separable model spaces containing all excitations with unperturbed energies up to 8h̄Ω. Using G matrices derived from a...

Test of shell-model interactions for nuclear structure calculations.

Recently no-core shell-model calculations have been performed @1,2#, in which all nucleons are active, so there are no hole states. This approach avoids the use of shell-model effective interactions involving excitations from an inert core of nucleons ~e.g., the core-polarization process!, and thereby avoids the convergence problems of the standard effectiveinteraction approach @3#. In this pap...

Ab Initio Nuclear Structure Theory with Chiral NN+3N Interactions

Low-energy nuclear theory has entered an era of ab initio nuclear structure and reaction calculations based on QCD. One of the most promising paths from QCD to nuclear observables employs Hamiltonians constructed within chiral effective field theory as starting point for precise ab initio studies. However, the full inclusion of chiral twoplus three-nucleon (NN+3N) interactions in exact and appr...

Convergence in the no-core shell model with low-momentum two-nucleon interactions

The convergence of no-core shell model calculations using renormalization group evolved low-momentum two-nucleon interactions is studied for light nuclei up to 7Li. Our results provide strict upper bounds for the ground-state energy at each value of the cutoff. Dramatic improvements in convergence are found at the lower cutoffs. Three-body interactions are not yet included in the renormalizatio...

Recent developments in no-core shell-model calculations

We present an overview of recent results and developments of the no-core shell model (NCSM), an ab initio approach to the nuclear many-body problem for light nuclei. In this approach, we start from realistic two-nucleon or twoplus threenucleon interactions. Many-body calculations are performed using a finite harmonicoscillator (HO) basis. To facilitate convergence for realistic inter-nucleon in...
