Abstract
With the help of a unified nuclear-structure–direct-reaction theory we analyze the reaction . The two halo neutrons are correlated through the bare and the induced (medium polarization) pairing interaction. By considering all dominant reaction channels leading to the population of the (2.69 MeV) first excited state of , namely, multistep transfer (successive, simultaneous, and nonorthogonality), breakup, and inelastic channels, it is possible to show that the experiment provides direct evidence of phonon mediated pairing.
