Abstract: (Elsevier B.V.)

The dineutron correlation is systematically studied in three different Borromean nuclei near the neutron dripline, ¹¹Li, ¹⁴Be and ¹⁷B, via the

(p, p n)

knockout reaction measured at the RIBF facility in RIKEN. For the three nuclei, the correlation angle between the valence neutrons is found to be largest in the same range of intrinsic momenta, which can be associated to the nuclear surface. This result reinforces the prediction that the formation of the dineutron is universal in environments with low neutron density, such as the surface of neutron-rich Borromean nuclei.
