The Hyperspherical Harmonics method: a tool for testing and improving nuclear interaction models

L. E. Marcucci, J. Dohet-Eraly, L. Girlanda +3

The Hyperspherical Harmonics (HH) method is one of the most accurate techniques to solve the quantum mechanical problem for nuclear systems with . In particular, by applyin…

Quasibound states of an antiproton and a hydrogen atom

Daniel Baye, Jérémy Dohet-Eraly

Accurate three-body quantal calculations of the system composed of a proton, an antiproton, and an electron are performed in perimetric coordinates with the Lagrange-mesh method, a…

Sensitivity of one-neutron knockout of halo nuclei to their nuclear structure

Chloë Hebborn, Pierre Capel

Halo nuclei are located far from stability and exhibit a very peculiar structure. Due to their very short lifetime, they are often studied through reactions. Breakup reactions are…

Simplified dynamical eikonal approximation

Chloë Hebborn, Daniel Baye

Background: Breakup reactions are often used to probe the nuclear structure of halo nuclei. The eikonal model diverges for Coulomb breakup since it relies on the adiabatic approxim…

Role of the symmetry energy and the neutron-matter stiffness on the tidal deformability of a neutron star with unified equations of state

Loic Perot, Nicolas Chamel, Aurélien Sourie

The role of the symmetry energy and the neutron-matter stiffness on the tidal deformability of a cold nonaccreted neutron star is studied using a set of unified equations of state.…

Beyond the proton drip line: Bayesian analysis of proton-emitting nuclei

Léo Neufcourt, Yuchen Cao, Samuel Giuliani +3

The limits of the nuclear landscape are determined by nuclear binding energies. Beyond the proton drip lines, where the separation energy becomes negative, there is not enough bind…

Transfer reactions with the Lagrange-mesh method

Shubhchintak, P. Descouvemont

We apply the -matrix method in Distorted Wave Born Approximation (DWBA) calculations. The internal wave functions are expanded over a Lagrange mesh, which provides an efficient…

Effect of Octupole correlations on Fission of Light Nuclei

Guillaume Scamps, Cédric Simenel

Fission of Hg produces mass asymmetric fragments which are expected to be influenced by deformed shell-effects at N=56 in the heavy fragment and Z=34 in the light fragment…

C: from Halo-EFT structure to the study of transfer, breakup and radiative-capture reactions

Laura Moschini, Jiecheng Yang, Pierre Capel

Aside from being a one-neutron halo nucleus, C is interesting because it is involved in reactions of relevance for several nucleosynthesis scenarios. The aim of this work is…

Sensitivity of one-neutron knockout to the nuclear structure of halo nuclei

Chloë Hebborn, Pierre Capel

Background: Information about the structure of halo nuclei are often inferred from one-neutron knockout reactions. Typically the parallel-momentum distribution of the remaining cor…

Microscopic three-cluster study of light exotic nuclei

P. Descouvemont

I develop a microscopic three-cluster model for exotic light nuclei. I use the hyperspherical formalism, associated with the Generator Coordinate Method. This model is well adapted…

Density-constraint Time-dependent Hartree-Fock-Bogoliubov method

G. Scamps, Y. Hashimoto

Background: The Density-constraint Time-dependent Hartree-Fock method is currently the tool of choice to predict fusion cross-sections. However, it does not include pairing correla…

Astrophysical -factor of the direct Li capture reaction in a three-body model

E. M. Tursunov, Daniel Baye, S. A. Turakulov

At the long-wavelength approximation, electric dipole transitions are forbidden between isospin-zero states. In an model with contributions, the Li astrop…
