The identification of α -clustered doorway states in ^44,48,52 Ti using machine learning

novel experimental analysis method has been developed, making use of the continuous wavelet transform and machine learning to rapidly identify α -clustering in nuclei in regions of high nuclear state density. This technique was applied to resonant scattering measurements of the ^4 He( ^40,44,48 Ca, α ) resonant reactions, allowing the α -cluster structure of ^44,48,52 Ti to be investigated. Fragmented α -clustering was identified in ^44 Ti and ^52 Ti, while the results for ^48 Ti were less conclusive, but suggest no such clustering.
