The spherical Hartree-Fock approximation is applied to the ab initio no-core shell model,
with a realistic effective nucleon-nucleon interaction in order to investigate the range of its …

We explore the impact of optimizations of the single-particle basis on the convergence
behavior and robustness of ab initio no-core shell model calculations of nuclei. Our focus is …

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 …

In this paper a state-of-the-art version of the nucleon-pair approximation to the nuclear shell
model is suggested. The configuration space is constructed by stepwise coupling collective …

The ab initio no-core shell model (NCSM) is extended to include a realistic three-body
interaction in calculations for p-shell nuclei. The NCSM formalism is reviewed and new …

Translationally invariant nuclear density is derived from the shell model one-body densities
by removing their spurious 0 ℏ Ω center-of-mass (cm) motion component. This paves the …

The ab initio no-core shell model (NCSM) is a well-established theoretical framework aimed
at an exact description of nuclear structure starting from high-precision interactions between …

The nuclear shell model has perhaps been the most important conceptual and
computational paradigm for the understanding of the structure of atomic nuclei. While the …

Background: It is well known that effective nuclear interactions are in general nonlocal. Thus
if nuclear densities obtained from ab initio no-core shell-model (NCSM) calculations are to …

Calculations in the ab initio no-core shell model (NCSM) have conventionally been carried
out using the harmonic-oscillator many-body basis. However, the rapid falloff (Gaussian …
