Decay protons from Mg energy levels populated through a previously reported
Mg(p, t)
Mg transfer reaction (Chae et al. in Phys Rev C 79:055804, 2009) have been analyzed for proton branching ratios as a follow-up analysis. The measurement was performed at the Holifield Radioactive Ion Beam Facility of Oak Ridge National Laboratory by utilizing 41-MeV proton beams and
Mg solid targets. Decay protons and reaction tritons were simultaneously detected with a silicon detector array. By investigating the
Mg(p, t)
Mg*(p)
Na channels, the proton branching ratios of five
Mg excited states were obtained. The measured branching ratios provide constraints on the proton partial widths of the populated
Mg levels, which have implications for X-ray burst nucleosynthesis.
