A unique decay process: beta delayed emission of a proton and a neutron by the Li halo nucleus

D. Baye, P. Descouvemont, E. M. Tursunov

The neutron-rich Li halo nucleus is unique among nuclei with known separation energies by its ability to emit a proton and a neutron in a decay process. The branching ra…

Beta delayed emission of a proton by a one-neutron halo nucleus

D. Baye, E. M. Tursunov

Some one-neutron halo nuclei can emit a proton in a beta decay of the halo neutron. The branching ratio towards this rare decay mode is calculated within a two-body potential model…

Self-interaction errors in nuclear energy density functionals

N. Chamel

When applied to a single nucleon, nuclear energy density functionals may yield a non-vanishing internal energy thus implying that the nucleon is interacting with itself. It is show…

Breakup reaction models for two- and three-cluster projectiles

D. Baye, P. Capel

Breakup reactions are one of the main tools for the study of exotic nuclei, and in particular of their continuum. In order to get valuable information from measurements, a precise…

Regularization of Multi-Reference Energy Density Functional Calculations

M. Bender, T. Duguet, P. -H. Heenen +1

We report the first application of a recently proposed regularization procedure for multi-reference energy density functionals, which removes spurious divergent or non-continuous c…

Spin and spin-isospin instabilities in asymmetric nuclear matter at zero and finite temperatures using Skyrme functionals

N. Chamel, S. Goriely

Self-consistent mean field methods based on phenomenological Skyrme effective interactions are known to exhibit spurious spin and spin-isospin instabilities both at zero and finite…

Further explorations of Skyrme-Hartree-Fock-Bogoliubov mass formulas. XII: Stiffness and stability of neutron-star matter

S. Goriely, N. Chamel, J. M. Pearson

We construct three new Hartree-Fock-Bogoliubov (HFB) mass models, labeled HFB-19, HFB-20, and HFB-21, with unconventional Skyrme forces containing and terms, i.e., dens…

Breathing-mode measurements in Sn isotopes and isospin dependence of nuclear incompressibility

J. M. Pearson, N. Chamel, S. Goriely

T. Li {\it et al.}[Phys. Rev. C {\bf 81}, 034309 (2010)] have analyzed their measured breathing-mode energies of some tin isotopes in terms of a first-order leptodermous expansion,…

Deducing spectroscopic factors from wave-function asymptotics

P. Capel, P. Danielewicz, F. M. Nunes

In a coupled-channel model, we explore the effects of coupling between configurations on the radial behavior of the wave function and, in particular, on the spectroscopic factor (S…

Influence of the halo upon angular distributions for elastic scattering and breakup

P. Capel, M. S. Hussein, D. Baye

The angular distributions for elastic scattering and breakup of halo nuclei are analysed using a near-side/far-side decomposition within the framework of the dynamical eikonal appr…

Effective contact pairing forces from realistic calculations in infinite homogeneous nuclear matter

Nicolas Chamel

Non-empirical effective contact pairing forces to be used in self-consistent mean-field calculations are presented. These pairing forces, constructed so as to reproduce exactly any…

Unified description of neutron superfluidity in the neutron-star crust with analogy to anisotropic multi-band BCS superconductors

N. Chamel, S. Goriely, J. M. Pearson +1

The neutron superfluidity in the inner crust of a neutron star has been traditionally studied considering either homogeneous neutron matter or only a small number of nucleons confi…

The R-matrix theory

P. Descouvemont, D. Baye

The different facets of the -matrix method are presented pedagogically in a general framework. Two variants have been developed over the years: The "calculable" -matrix…
