Abstract

The breakup of 24Mg into 16O and8Be fragments has been studied using the reactions 12C(24Mg, 16O8Be) 12C and 12C(20Ne, 16O8Be) 8Be. In the latter case, discrete states are observed near 24–28 MeV of excitation in 24Mg and the yield from this reaction is an order of magnitude greater than that of the former. This implies the excited configuration populated in 24Mg is favoured by the transfer of an alpha-particle and would therefore suggest an association with a 4-particle 4-hole configuration. This suggests a link with the octupole stabilised deformed minimum which appears in Nilsson-Strutinsky calculations of the potential energy surface in 24Mg, and also with the α - 16O - α structure predicted in cranked cluster model calculations. In the excitation spectrum no states appear above 31 MeV indicating a possible band termination in disagreement with recent results using the 16O+ 12C reaction. These results are discussed in terms of the Harvey model.
