Abstract

The decay branchings of a resonance in the C-12(C-12,gamma)Mg-24 reaction at E-c.m. = 8.0 MeV have been studied with high resolution using the Gammasphere array. Radiative capture residues were discriminated from scattered beam and the dominant evaporation channels using the fragment mass analyzer coupled to a multistage Parallel Grid Avalanche Counter (PGAC)/ion chamber system. The clean selection of residues has allowed the population of excited states up to 10 MeV in Mg-24 to be examined in detail. Strong feeding of an excited K-pi = 0(-) band is observed. A J(pi) = 4(+) assignment to the resonance is strongly favored.
