Collisions involving 112Sn and 124Sn nuclei have been simulated with the improved Quantum Molecular Dynamics transport model. The results of calculations reproduce isospin diffusion data from two different observables ratios neutron proton spectra. By comparing these to performed over a range symmetry energies at saturation density representations dependence energy, constraints on energy sub-normal are obtained. Results present work compared put forward in other recent analysis.
