Description of the 11Li(p, d)10Li transfer reaction using structure overlaps from a full three-body model

Recent data on the differential angular distribution for the transfer reaction Li-11(p, d) Li-10 at E/A = 5.7MeVin inverse kinematics are analyzed within the DWBA reaction framework, using the overlap functions calculated within a three-body model of Li-11. The weight of the different Li-10 configurations in the system's ground state is obtained from the structure calculations unambiguously. The effect of the 9Li spin in the calculated observables is also investigated. We find that, although all the considered models succeed in reproducing the shape of the data, the magnitude is very sensitive to the content of p(1/2)wave in the Li-11 ground-state wave function. Among the considered models, the best agreement with the data is obtained when the Li-11 ground state contains a similar to 31% of p(1/2)wave in the n-Li-9 subsystem. Although this model takes into account explicitly the splitting of the 1(+) and 2(+) resonances due to the coupling of the p(1/2)wave to the 3/2(-)spin of the core, a similar degree of agreement can be achieved with a model in which the Li-9 spin is ignored, provided that it contains a similar p-wave content.
