With the help of a unified nuclear-structure-direct-reaction theory we analyze the reaction {sup 1}H({sup 11}Li,{sup 9}Li){sup 3}H. 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 1/2{sup -} (2.69 MeV) first excited state of {sup 9}Li, 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.
