A quantitative comparison regarding absolute cross sections associated to Statistical and Dynamical Fission in the system 124Sn+64Ni and112Sn+58Ni experimentally investigated at 35 AMeV beam energy is presented. It results that Dynamical Fission process is about two times more probable in the neutron rich 124Sn+64Ni system than in the 112Sn+58Ni neutron poor one. At this point of our analysis it is not clear if the observed difference is originated by different entrance channel Isospin (N/Z) content or by different size between the two investigated systems.
