Microscopic analysis of nucleus-nucleus elastic scattering at intermediate energies
نویسنده
چکیده
2014 An effective nucleon-nucleon amplitude for bound nucleons taking into account medium effects such as Fermi motion and Pauli blocking has been derived from the Bethe-Goldstone equation, using a MonteCarlo simulation of a nucleon-nucleon collision in the nuclear medium. The obtained amplitude is local and density dependent. This amplitude has been used in a local density approximation to analyse microscopically nucleus-nucleus elastic scattering at intermediate energies. The coupling to low-lying collective states has been explicitly included. This parameter free analysis reproduces reasonably well the experimental data down to an energy of 30and up to 200 MeV/nucleon. J.

Relativistic microscopic description of proton-nucleus scattering at intermediate energies.
We study elastic proton-nucleus scattering at intermediate energies. The nucleon-nucleus optical potential is derived from the Bonn nucleon-nucleon potential and the Dirac-Brueckner approach for nuclear matter. Our calculations , which do not contain any adjustable parameters, yield good agreement with experiment.
متن کاملNeutron scattering measurements at intermediate energies
The study of elastic neutron scattering at intermediate energies is essential for the understanding of the isovector term in the nucleon-nucleus interaction, as well as for the development of macroscopic and microscopic optical potentials at these energies. The techniques used for neutron scattering measurements is presented in this paper, as well as the di culties encountered. The few faciliti...
متن کاملK − - Nucleus Scattering at Low and Intermediate Energies
We calculate K −-nucleus elastic differential, reaction and total cross sections for different nuclei (12 C, 40 Ca and 208 Pb) at several laboratory antikaon momenta, ranging from 127 MeV (momentum of an antikaon produced in the φ-meson decay) to 800 MeV. We use different antikaon-nucleus optical potentials, some of them fitted to kaonic atom data, and study the sensitivity of the results to th...
متن کاملA computer program for nuclear scattering at intermediate and high energies
C.A. Bertulani, C.M. Campbell and T. Glasmacher National Superconducting Cyclotron Laboratory, Michigan State University, E. Lansing, MI 48824 (Dated: July 29, 2009) Abstract A computer program is presented which calculates the elastic and inelastic scattering in intermediate and high energy nuclear collisions. A coupled-channels method is used for Coulomb and nuclear excitations of E1, E2, E3,...
متن کاملNeutron skin of Pb in consistency with neutron star observations
The renormalized meson-nucleon couplings are applied to the relativistic optical model of p-208Pb elastic scattering at Tlab = 200MeV. We calculate the strength of the vector potential at nuclear center as varying the neutron radius of 208Pb. The neutron skin thickness Sn is determined in the comparison of the calculated potential with the phenomenological one. We nd a value Sn = 0:118fm being...
