Abstract
The core longitudinal momentum distributions in two-neutron stripping reactions for halo nuclei of 20C and 22C are computed and compared to the experimental data obtained by detecting the core nucleus. The three-body wave function from the zero-range renormalized model is used as input in our calculations. We approximate the wave function of the projectile with a three-body structure, namely neutron-neutron-core, to an effective two-body one by integrating over neutron-neutron relative distance, such that the one has a core-dineutron wave function. The eikonal approximation is used in the description of the fragment-target interactions where the São Paulo optical potential is used for modeling the core-target and a Woods-Saxon potential is used for the dineutron-target interaction.
