Abstract

Quasi-elastic scattering data were obtained for the radioactive nucleus ⁸Li on a ⁹⁰Zr target at the near-barrier energy of 18.5MeV over the angular range $\theta_{lab}=15^{\circ}$ to 80^°. They were analyzed within the coupled channels and coupled reaction channels frameworks pointing to a strong coupling effect for single neutron stripping, in contrast to ^{6, 7} Li + ⁹⁰ Zr elastic scattering at similar energies, a non-trivial result linked to detailed differences in the structure of these Li isotopes.
