Abstract
Nuclear break-up is a powerful tool to investigate nuclear structure as it is sensitive to the quantum properties of the emitted particles. This reaction mechanism has been used to investigate several aspects of correlations. First, the case of 11 Be was studied where the spectroscopic factors for the two configurations where extracted. Secondly, the spectroscopic factor for alpha clusterization in the ground state of 40 Ca was measured. Finally the correlation between the two neutrons in the halo of 6 He emitted through break- up reactions showed strong contribution for the di-neutron configuration.

Among all other inelastic processes leading to the emission of one nucleon, the nuclear break-up, called Towing Mode is characterized by the emission of a nucleon from the target on the same side as the projectile with an intermediate velocity and a large angle with respect to the beam axis
The mechanism is understood the following way: when the projectile passes by the target, the nucleon inside the target feels its nuclear potential and is towed to be emitted to the continuum. This picture is confirmed by a theoretical model solving the time dependent Schrödinger equation (TDSE) for the wave function of a nucleon inside the potential of target when the projectile potential passes by
