The 19F(α,2He)21F reaction was investigated at 55 MeV incident energy. The transferred angular momenta of prominent transitions excited were determined from a distorted wave Born analysis of the angular distributions. Tentative spin assignments for the observed levels are extracted from shell-model calculations with the “unified” sd-space interaction based on the very good reproduction of the excitation energies and the predicted large two-neutron transfer spectroscopic factors.
