Abstract: 3A.00006 : Modeling nuclear stopping with in-medium modifications of nucleon-nucleon cross sections.
(NSCL and Department of Physics and Astronomy, Michigan State University)
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 include momentum anisotropy, linear momentum transfer, and isospin tracing. The data clearly shows that modeling the transport with free elementary cross-sections is inaccurate and reduced cross-sections are required. Reduction of the cross-sections produce an increase in transport coefficients of nuclear matter, compared to calculations based on free cross-sections.
