Abstract: We present the centrality dependence of proton and deuteron rapidity distributions in Ru+Ru collisions at 400A MeV. Data are compared with Isospin Quantum Molecular Dynamics calculations (IQMD) under various assumptions on the nucleon-nucleon cross-section in the medium. The rapidity spectra of both particles can be reproduced by IQMD with a free nucleon-nucleon cross-section for the most central collisions. The ratio of baryon rapidity distributions in isospin asymmetric collision systems shows incomplete mixing and partial transparency of both the projectile and target nuclei at this beam energy.
