On the nuclear symmetry energy and the neutron skin in neutron-rich nuclei
A. E. L. Dieperink, Y. Dewulf, D. Van Neck +2
The symmetry energy for nuclear matter and its relation to the neutron skin in finite nuclei is discussed. The symmetry energy as a function of density obtained in a self-consisten…
Electromagnetic interaction in chiral quantum hadrodynamics and decay of vector and axial-vector mesons
A. Yu. Korchin, D. Van Neck, M. Waroquier
The chiral invariant QHD-III model of Serot and Walecka is applied in the calculation of some meson properties. The electromagnetic interaction is included by extending the symmetr…
Coherent Compton scattering on light nuclei in the delta resonance region
L. Van Daele, A. Yu. Korchin, D. Van Neck +2
Coherent Compton scattering on light nuclei in the delta resonance region is studied in the impulse approximation and is shown to be a sensitive probe of the in-medium properties o…
Improved lower bounds for the ground-state energy of many-body systems
D. Van Neck, Y. Dewulf, M. Waroquier
New lower bounds for the binding energy of a quantum-mechanical system of interacting particles are presented. The new bounds are expressed in terms of two-particle quantities and…
Short-range correlations in nuclear matter using Green's functions within a discrete pole approximation
Y. Dewulf, D. Van Neck, M. Waroquier
We treat short-range correlations in nuclear matter, induced by the repulsive core of the nucleon-nucleon potential, within the framework of a self-consistent Green's function theo…
Production of e+e- pairs in proton-deuteron capture to 3He
A. Yu. Korchin, D. Van Neck, M. Waroquier +2
The process p+d \leftrightarrow 3He + γ* at intermediate energies is described using a covariant and gauge-invariant model, and a realistic pd3He vertex. Both photodisintegration o…
Center-of-mass effects on the quasi-hole spectroscopic factors in the 16O(e,e'p) reaction
D. Van Neck, M. Waroquier, A. E. L. Dieperink +2
The spectroscopic factors for the low-lying quasi-hole states observed in the 16O(e,e'p)15N reaction are reinvestigated with a variational Monte Carlo calculation for the structure…
Electroinduced two-nucleon knockout and correlations in nuclei
J. Ryckebusch, V. Van der Sluys, K. Heyde +4
We present a model to calculate cross sections for electroinduced two-nucleon emission from finite nuclei. Short-range correlations in the wave functions and meson-exchange contrib…
Long-range correlations in finite nuclei: comparison of two self-consistent treatments
Y. Dewulf, D. Van Neck, L. Van Daele +1
Long-range correlations, which are partially responsible for the observed fragmentation and depletion of low-lying single-particle strength, are studied in the Green's function for…
Short-range correlations in (e,ep) and (e,epp) reactions on complex nuclei
Jan Ryckebusch, Marc Vanderhaeghen, Kris Heyde +1
The influence of short-range correlations (SRC) on the triple-coincidence (e,epp) reactions is studied. The non-relativistic model uses a mean-field potential to account for the…
Absorption mechanisms in photon induced two-body knockout
L. Machenil, M. Vanderhaeghen, J. Ryckebusch +1
Calculations have been performed for the O(,pn) and the O(,pp) reaction in the photon-energy range = 60-300 MeV. Besides the contribution from the more co…
