Isospin transport properties in nuclear matter: Light clusters as isospin tracker

International audienceThe study of transport properties is a key point to determine energy dissipation and isospin transport for heavy-ion–induced collisions in the Fermi energy domain. This can be achieved by measuring the nuclear stopping linked to the in-medium mean free path λ∗ NN of nucleons in nuclear matter. The quantities are also a good probe to constrain the phenomenological and theoretical models of the nucleon-nucleon interaction in nuclear matter. In this talk, we present new simulations for light A = 3 clusters (3H, 3He) compared to experimental data on a large-scale analysis, coming from the INDRA 4π array. By looking at the velocities distributions of the light clusters, we demonstrate that we are able to get consistent information concerning the transport properties of nucleons in nuclear matter
