Single-nucleon transfer to unbound states in the [Formula Presented] reaction at incident energies of 120, 160, and 200 MeV

The [Formula Presented] reaction was investigated at incident energies of 120, 160, and 200 MeV in order to resolve discrepancies found between previous measurements and theoretical predictions for the analogous reaction [Formula Presented] at these energies. The line shapes of the [Formula Presented] ground-state resonance in the measured triton energy spectra are well reproduced by distorted-wave Born approximation (DWBA) calculations. Cluster-core optical potentials, which yield better overall agreement both for [Formula Presented] elastic scattering and for the single-nucleon transfer reactions, are presented. It is shown that the previously observed discrepancies in magnitude between measured and calculated cross sections by a factor of [Formula Presented] can be improved by employing spectroscopic factors obtained from a realistic shell model for the transitions to the final mass-3 and mass-5 systems.
