Modeling nuclear stopping with in-medium nucleon-nucleon cross sections
Stopping in heavy ion collisions is investigated with the aim of understanding microscopic dynamics of collisions and transport properties of nuclear matter. Boltzmann-equation simulations are compared to available data on stopping in the energy range between 0.02 A and 1.5 A GeV. Stopping observables used in comparisons include momentum anisotropy, linear momentum transfer, and isospin tracing...
متن کاملMicroscopic calculation of in-medium nucleon-nucleon cross sections.
We derive in-medium nucleon-nucleon (NN) cross sections in a microscopic model. Our calculations are based upon the Bonn NN potential and the Dirac-Brueckner approach for nuclear matter. We consider energies up to 300 MeV (in the laboratory frame) and densities up to twice nuclear matter density. Our results deviate substantially from cross section parametrizations that are commonly used in the...
متن کاملDensity dependence of in-medium nucleon-nucleon cross sections
The lowest-order correction of the density dependence of in-medium nucleonnucleon cross sections is obtained from geometrical considerations of Pauliblocking effects. As a by-product, it is shown that the medium corrections imply an 1/E energy dependence of the density-dependent term. PACS: 25.70.-z,25.75.Ld The nucleon-nucleon cross section is a fundamental input in theoretical calculations of...
متن کاملEquation of State and Nucleon-Nucleon Cross Section in Medium
The equation of State (EOS) and nucleon-nucleon (NN) cross section in medium have been studied, using the antisymmetrized molecular dynamics model (AMD-V) of Ono et al. [1]. The model has been successfully applied to the Zn + Ni reaction at 35A to 79A MeV [2]. In the previous analysis in reference [2] the Gogny force and an empirical NN cross section were used to reproduce the experimental resu...
متن کاملNucleon-Nucleon Cross Sections in Nuclear Matter
We provide a microscopic calculation of neutron-proton and neutron-neutron cross sections in symmetric nuclear matter at various densities, using the Brueckner-Hartree-Fock approximation scheme with the Paris potential. We investigate separately the medium eeects on the eeective mass and on the scattering amplitude. We determine average cross sections suitable for application in the dynamical s...
