Abstract

The six-α decay of Mg has been studied via the reaction 13N+ 11B at two beam energies, 29.5 MeV and 45 MeV. Large detector arrays allowed this reaction to be studied with low intensity radioactive N beam. The excitation energy in the Mg* was in the region of the 46 MeV resonance in C+ C scattering. From the six-α particles, events of interest were selected by associating two of the α particle pairs as the decay products of Be. The c.m. energy spectra for two Be+two α events have been extracted. The analysis revealed that most of these events originate from C-+ C-. The total cross section for these six-α events has been extracted at the two beam energies.
