Final-State Interactions in (e,e'p) Reactions with Polarized Nuclei
J. E. Amaro, T. W. Donnelly
The cross section for coincidence, quasielastic proton knock-out by electrons from a polarized K39 nucleus is computed in DWIA using an optical potential in describing the wave fun…
Tensor interaction in Hartree--Fock calculations
Giampaolo Co', Antonio M. Lallena
The contribution of the tensor interaction in Hartree-Fock calculations for closed shell nuclei is studied. The investigation is done neglecting the spin-orbit component of the for…
Bethe-Salpeter Approach for Meson-Meson Scattering in Chiral Perturbation Theory
Juan Nieves, Enrique Ruiz Arriola
The Bethe-Salpeter equation restores exact elastic unitarity in the s- channel by summing up an infinite set of chiral loops. We use this equation to show how a chiral expansion ca…
Relativistic Effects in Electromagnetic Meson-Exchange Currents for One-Particle Emission Reactions
J. E. Amaro, M. B. Barbaro, J. A. Caballero +2
Following recent studies of non-relativistic reductions of the single-nucleon electromagnetic current operator, here we extend the treatment to include meson exchange current opera…
Inclusive quasielastic scattering of polarized electrons from polarized nuclei
J. E. Amaro, J. A. Caballero, T. W. Donnelly +1
The inclusive quasielastic response functions that appear in the scattering of polarized electrons from polarized nuclei are computed and analyzed for several closed-shell-minus-on…
A model of short-range correlations in the charge response
J. E. Amaro, A. M. Lallena, G. Co' +1
The validity of a model treating the short-range correlations up to the first order is studied by calculating the charge response of an infinite system and comparing the obtained r…
