Importance Truncated No-Core Shell Model
One of the most universal tools for the ab initio solution of the nuclear many-body problem is the No-Core Shell Model (NCSM). It is widely used for the description of ground states and low-lying excited states of nuclei throughout the p-shell [1]. Apart from energies, detailed spectroscopic information and form-factors can be extracted from the resulting many-body eigenstates. The limitation o...
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 کاملShortcuts to Nuclear Structure: Lessons in Hartree-fock, Rpa, and the No-core Shell Model
While the no-core shell model is a state-of-the-art microscopic approach to low-energy nuclear structure, its intense computational requirements lead us to consider timehonored approximations such as the Hartree-Fock (HF) approximation and the random phase approximation (RPA). We review RPA and point out some common misunderstandings, then apply HF+RPA to the no-core shell model. Here the main ...
متن کاملRecent 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...
متن کاملAuxiliary potential in no-core shell-model calculations.
The Lee-Suzuki iteration method is used to include the folded diagrams in the calculation of the two-body effective interaction v (2) eff between two nucleons in a no-core model space. This effective interaction still depends upon the choice of single-particle basis utilized in the shell-model calculation. Using a harmonic-oscillator single-particle basis and the Reid-soft-core NN potential, we...
