Abstract
Measurements of the 12C( 16O, 20Neα)α, 12C( 16O,αα) 20Ne, 12C( 16O, 8Be) 20Ne and 12C( 16O, 16Oα) 8Be reactions have been performed at E c.m. = 27.0 MeV. For decays proceeding through resonant states in the intermediate 24Mg nucleus, angular correlation measurements have enabled spin assignments to be made and the dominant entrance channel angular momentum to be determined. The results are inconsistent with recent similar experiments which were interpreted as arising from successive α-decays from deformed shape isomeric states in 28Si and 24Mg.
