In-medium effects around the Fermi energy

Abstract

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.
