In the present work, we initiated a systematic study of neutron-induced fission reactions using the code CoMD (Constrained Molecular Dynamics) of A. Bonasera and M. Papa [1,2]. The code implements an effective interaction with a nuclear-matter compressibility of K=200 (soft EOS) with several forms of the density-dependence of the nucleon symmetry potential. In addition, CoMD imposes a constraint in the phase space occupation for each nucleon restoring the Pauli principle at each time step of the collision). Proper choice of the surface parameter of the effective interaction has been made to describe fission. In this poster, we presented preliminary results of neutron-indued fission on 235U at neutron energies 5, 10, 15, 25, 50 and 100 MeV. Calculated mass and energy distributions are shown and compared with the recent experimental data of Loveland et al. [3]. It appears that the microscopic code CoMD is able to describe the complicated many-body dynamics of the n-induced fission process. Proper adjustment of the parameters of the effective interaction and further improvements of the code will be implemented to achieve a satisfactory description of the experiment data. (EN)
