Clustering in \(^{18}\)O -- absolute determination of branching ratios via high-resolution particle spectroscopy

The determination of absolute branching ratios for high-energy states in light nuclei is an important and useful tool for probing the underlying nuclear structure of individual resonances: for example, in establishing the tendency of an excited state towards \(\alpha\)-cluster structure.

Summary:The determination of absolute branching ratios for high-energy states in light nuclei is an important and useful tool for probing the underlying nuclear structure of individual resonances: for example, in establishing the tendency of an excited state towards \(\alpha\)-cluster structure. Difficulty arises in measuring these branching ratios due to similarities in available decay channels, such as (\(\mathbf{^{18}}\)O,\(\mathbf{n}\)) and (\(\mathbf{^{18}}\)O,\(\mathbf{2n}\)), as well as differences in geometric efficiencies due to population of bound excited levels in daughter nuclei. Methods are presented using Monte Carlo techniques to overcome these issues.
