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.
