Energy dependence of non-local potentials

A. E. Lovell, P. -L. Bacq, P. Capel +2

Recently a variety of studies have shown the importance of including non-locality in the description of reactions. The goal of this work is to revisit the phenomenological approach…

Hyperspherical harmonics expansion on Lagrange meshes for bosonic systems in one dimension

N. K. Timofeyuk, D. Baye

A one-dimensional system of bosons interacting with contact and single-Gaussian forces is studied with an expansion in hyperspherical harmonics. The hyperradial potentials are calc…

Isospin-forbidden electric-dipole capture and the Li reaction

Daniel Baye, E. M. Tursunov

At the long-wavelength approximation, transitions are forbidden between isospin-zero states. Hence radiative capture is strongly hindered in reactions involving n…

Updated three-body model of He decay into the + continuum

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

The -decay process of the He halo nucleus into the continuum is studied in an updated three-body model. The He nucleus is described as an system in hypersp…

Analysis of corrections to the eikonal approximation

Chloë Hebborn, Pierre Capel

Various corrections to the eikonal approximations are studied for two- and three-body nuclear collisions with the goal to extend the range of validity of this approximation to beam…

Double-folding potentials from chiral effective field theory

V. Durant, P. Capel, L. Huth +2

The determination of nucleus-nucleus potentials is important not only to describe the properties of the colliding system, but also to extract nuclear-structure information and for…

Four-body continuum effects in 11Be+d scattering

Pierre Descouvemont

We present a new reaction model, which permits the description of reactions where both colliding nuclei present a low threshold to breakup. The method corresponds to a four-body ex…

Reconciling Coulomb breakup and neutron radiative capture

Pierre Capel, Yvan Nollet

The Coulomb-breakup method to extract the cross section for neutron radiative capture at astrophysical energies is analyzed in detail. In particular, its sensitivity to the descrip…
