ABSTRACT
The nuclear break-up of 6He on a 208Pb target was studied at 20AMeV using a secondary beam
of 6He produced by the SPIRAL facility at GANIL. α-particles were detected in coincidence with two
neutrons with a large angular coverage and the reaction mechanism was identified. From the distribution
of the relative angles between the two neutrons the correlation function was extracted. It shows a strong
correlation at small relative angles attributed to the contribution of the
di-neutron configuration of 6He.
