Phaseshift equivalent NN potentials and the deuteron

A. Polls, H. Müther, R. Machleidt +1

Different modern phase shift equivalent NN potentials are tested by evaluating the partial wave decomposition of the kinetic and potential energy of the deuteron. Significant diffe…

Asymmetric semi-infinite nuclear matter: surface and curvature properties in relativistic and non-relativistic models

M. Centelles, M. Del Estal, X. Vinas

Surface and curvature properties of asymmetric nuclear matter are studied beyond the proton drip. Using the semiclassical extended Thomas-Fermi method, the calculations are perform…

Non perturbative chiral approach to s-wave \bar{K}N interactions

E. Oset, A. Ramos

The s-wave meson-nucleon interaction in the sector is studied by means of coupled-channel Lippmann Schwinger equations, using the lowest order chiral Lagrangian and a cut…

Nuclear Sizes and the Isotope Shift

J. L. Friar, J. Martorell, D. W. L. Sprung

Darwin-Foldy nuclear-size corrections in electronic atoms and nuclear radii are discussed from the nuclear-physics perspective. Interpretation of precise isotope-shift measurements…

Modern nucleon-nucleon potentials and symmetry energy in infinite matter

L. Engvik, M. Hjorth-Jensen, R. Machleidt +2

We study the symmetry energy in infinite nuclear matter employing a non-relativistic Brueckner-Hartree-Fock approach and using various new nucleon-nucleon (NN) potentials, which fi…

Correlations and the Cross Section of Exclusive () Reactions for O

K. Amir-Azimi-Nili, J. M. Udias, H. Müther +2

The reduced cross section for exclusive () reactions has been studied in DWIA for the example of the nucleus O using a spectral function containing effects of correla…

On the Dirac Structure of the Nucleon Selfenergy in Nuclear Matter

A. Trasobares, A. Polls, A. Ramos +1

The relativistic structure of the self-energy of a nucleon in nuclear matter is investigated including the imaginary and real components which arise from the terms of first and sec…
