Isospin dynamics and nuclear dipolar degree of freedom

The strong connection between the dipolar signal as obtained from the measured velocities and charge of all fragments produced in a heavy collision and the dynamics of the isospin equilibration processes is illustrated. Effects due to both statistical and dynamical mechanisms are shortly discussed. Experimental data related to semi-peripheral collisions induced on the 48Ca + 27Al at 40 MeV/nucleon system are also shown and compared with CoMD-III calculations
