Abstract

A study of the Li-7(Be-9, (HeBe)-He-4-Be-9)H-3 reaction at E-beam = 70 MeV has been performed using resonant particle spectroscopy techniques and provides a measurement of alpha-decaying states in C-13. Excited states are observed at 12.0, 13.4, 14.1, 14.6, 15.2, 16.8, 17.9, 18.7, 21.3 and 23.9 MeV. This study provides the first measurement of the three highest energy states. Angular distribution measurements have been performed and have been employed to indicate the transferred angular momentum for the populated states. These data are compared with recent speculations of the presence of chain-like structures in C-13. Crown Copyright (C) 2003 Published by Elsevier B.V. All rights reserved.
