Abstract
The region of excitation in near 9.85 MeV has been investigated for evidence of a doublet, expected from tetrahedral symmetry arguments, by using the He,O and HeHeC reactions. Energy-matched measurements of the pair of reactions show no evidence for cascade gamma-ray decay of any but the known D-wave resonance observed in the elastic channel. The gamma-ray decay width of a possible second nondegenerate level to the state is determined to be less than 5× eV.
