“…above the Fermi energy, we note a continuous decrease of λ NN , whatever the system size, toward an asymptotic value corresponding to λ NN = 4.5 ± 1 fm above 100 A MeV. These values are compatible with both experimental data [24,25] and recent theoretical studies [17] around and above 100 A MeV. This agreement also suggests that the characteristic length L is indeed closely related to the nuclear radius of the colliding system and justifies a posteriori our assumption.…”

We study nuclear stopping in central collisions for heavy-ion induced reactions in the Fermi energy domain (15-100 A MeV). Using the large dataset provided by the 4π array INDRA, we determine that stopping can be directly related to the transport properties in the nuclear medium. By looking specifically at protons, we present a comprehensive body of experimental results concerning the mean free path, the nucleon-nucleon cross-section and in-medium effects in nuclear matter.

“…With that in mind, the prime purpose of this paper is to compare in detail results obtained from the global DP model with those from the g-folding model for proton scattering. First we report on results of predictions of angular observables for elastic scattering of 65 MeV and of 200 MeV protons from 12 C, 16 O, 40 Ca, 90 Zr, and 208 Pb. For all cases, the results of the calculations made were plotted before any data was added.…”

“…The global DP approach, based on the relativistic impulse approximation (RIA), fits the data well when proton and neutron densities, their root-mean-square radii, and the neutron skin thickness, all are credible. Targets of 40 Ca, 48 Ca and 208 Pb were considered [9]. However, the two models fundamentally are different.…”

Comparison of optical model results from a microscopic Schrödinger approach to nucleon-nucleus elastic scattering with those from a global Dirac phenomenology

Comparisons are made between results of calculations for intermediate energy nucleon-nucleus scattering for 12 C, 16 O, 40 Ca, 90 Zr, and 208 Pb, using optical potentials obtained from global Dirac phenomenology and from a microscopic Schrödinger model. Differential cross sections and spin observables for scattering from the set of five nuclei at 65 MeV and 200 MeV have been studied to assess the relative merits of each approach. Total reaction cross sections from proton-nucleus and total cross sections from neutron-nucleus scattering have been evaluated and compared with data for those five targets in the energy range 20 MeV to 800 MeV. The methods of analyses give results that compare well with experimental data in those energy regimes for which the procedures are suited.

“…Taking the spread between different lines as an estimate of theoretical uncertainties, one estimates errors to be less than 1 fm beyond 50 MeV. This uncertainty is of the same order of that obtained from experimental estimates [12,13].…”

Abstract. A microscopic determination of the mean-free path of a nucleon in symmetric nuclear matter is presented. Calculations are based on self-consistent Green's functions theory within the ladder approximation and use different realistic nucleon-nucleon potentials supplemented by semi-phenomenological three-body forces. Temperature and density dependence are discussed. At zero temperature and nuclear saturation density we find that, for energies above 50 MeV, a nucleon has a mean-free path of 4 to 5 fermi.
