Abstract

The12C(4He,8Be)8Be reaction has been measured with a beam energy ranging from 12.2 to 20.0 MeV. The α-particles emitted in the decay of 8Be were detected in an array of four double sided silicon strip detectors. The excitation function for events in which the 8Be centre of mass angle θcm 90° provides evidence that the previously observed 6+ resonance at an excitation energy of 19.35 MeV in 16O is a 6+ doublet, with members at ∼ 19.30 and 19.37 MeV. © Published under licence by IOP Publishing Ltd.
