Extending the Eikonal Approximation to Low Energy

Pierre Capel, Tokuro Fukui, Kazuyuki Ogata

E-CDCC and DEA, two eikonal-based reaction models are compared to CDCC at low energy (e.g. 20AMeV) to study their behaviour in the regime at which the eikonal approximation is supp…

Effect of three-body forces on response functions in infinite neutron matter

D. Davesne, J. W. Holt, A. Pastore +1

We study the impact of three-body forces on the response functions of cold neutron matter. These response functions are determined in the random phase approximation (RPA) from a re…

Beyond mean-field study of elastic and inelastic electron scattering off nuclei

J. M. Yao, M. Bender, P. -H. Heenen

Electron scattering provides a powerful tool to determine charge distributions and transition densities of nuclei. This tool will soon be available for short-lived neutron-rich nuc…

Linear response theory and neutrino mean free path using Brussels-Montreal Skyrme functionals

A. Pastore, M. Martini, D. Davesne +3

The Brussels-Montreal Skyrme functionals have been successful to describe properties of both finite nuclei and infinite homogeneous nuclear matter. In their latest version, these f…

Tools for incorporating a D-wave contribution in Skyrme energy density functionals

P. Becker, D. Davesne, J. Meyer +2

The possibility of adding a D-wave term to the standard Skyrme effective interaction has been widely considered in the past. Such a term has been shown to appear in the next-to-nex…

Beyond Mean-Field Calculations for Odd-A Nuclei

B. Bally, B. Avez, M. Bender +1

Beyond mean-field methods are very successful tools for the description of large-amplitude collective motion for even-even atomic nuclei. The state-of-the-art framework of these me…

Comparison of potential models of nucleus-nucleus bremsstrahlung

Jérémy Dohet-Eraly, Daniel Baye

At low photon energies, the potential models of nucleus-nucleus bremsstrahlung are based on electric transition multipole operators, which are derived either only from the nuclear…
