A kinematically complete experiment has been performed to study the -n final-state interaction (FSI) in the + d + p + n break-up reaction at 50 MeV incident energy for the alpha-particles. For this, we have chosen four pairs of correlation angles for the outgoing alpha and protons. These are ( , ), ( , ), ( , ) and ( , ), selected kinematically where the allowed phase spaces are in favor of the -n final-state interaction. Our experimental data show strong -n FSI in all the selected configurations. Also, the FSI is found to be stronger at the lower alpha-particle energy when two FSI peaks appear in the same configuration.
