Recent data on the differential angular distribution for the transfer reaction 11 Li(p,d) 10 Li at E/A = 5.7 MeV in inverse kinematics are analyzed within the DWBA reaction framework, using the overlap functions calculated within a three-body model of 11 Li. The weight of the different 10 Li configurations in the system's ground state is obtained from the structure calculations unambiguously. The effect of the 9 Li 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 11 Li ground-state wave function. Among the considered models, the best agreement with the data is obtained when the 11 Li ground state contains a ∼31% of p 1/2 wave in the n-9 Li 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 9 Li spin is ignored, provided that it contains a similar p-wave content.
A campaign of intermediate energy (300-450 MeV/u) proton-induced nucleon knockout measurements in inverse kinematics has been recently undertaken at the R 3 B/LAND setup at GSI. We present a systematic theoretical analysis of these data with the aim of studying the quenching of the single-particle strengths and its binding-energy dependence. For that, the measured semi-inclusive (p, 2p) and (p, pn) cross sections are compared with theoretical predictions based on single-particle cross sections derived from a novel coupled-channels formalism and shell-model spectroscopic factors. A systematic reduction of about 20-30% is found, with a very limited dependence on proton-neutron asymmetry.
