Abstract
Decay protons from \(^{22}\)Mg energy levels populated through a previously reported \(^{24}\)Mg(p, t)\(^{22}\)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 \(^{24}\)Mg solid targets. Decay protons and reaction tritons were simultaneously detected with a silicon detector array. By investigating the \(^{24}\)Mg(p, t)\(^{22}\)Mg*(p)\(^{21}\)Na channels, the proton branching ratios of five \(^{22}\)Mg excited states were obtained. The measured branching ratios provide constraints on the proton partial widths of the populated \(^{22}\)Mg levels, which have implications for X-ray burst nucleosynthesis.
