Nucleon-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...
متن کاملModeling 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 کاملEnergy dependence of nucleon-nucleon inelastic total cross-sections
Total inelastic pp cross-sections are reconstructed for laboratory kinetic energies ranging from 0.3 to 400 GeV. They are obtained by fitting together the sum of total cross-sections for exclusive inelastic channels, the sum of topological cross-sections and the results for independent « direct » measurements. The inelastic np cross-sections are reconstructed in the energy range below 4.2 GeV u...
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 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...
