Heavy ion radiative capture: C-12(C-12,gamma)

The heavy ion radiative capture reaction C-12(C-12,gamma) has been investigated around a beam energy of 16 MeV. The total cross-section has been measured with the Fragment Mass Analyser at Argonne National Laboratory and found to be somewhat larger than has previously been measured. A subsequent measurement with the Gammasphere array has shown that a considerable proportion of this extra cross-section relates to a highly non-statistical decay through high-lying states in (24)mg.
