已经开发出一种新技术，利用连续小波变换来识别
高核态密度区域中共振散射测量的 α 簇态。
该技术加快了中等质量和重原子核中 α 簇的研究，其中
人们对 α 簇在细胞核结构中所起的作用知之甚少。在此我们报道
将该技术应用于 4He(40,44,48Ca,α) 共振反应的测量，
评估 44,48,52Ti 的 α 簇结构。在 44Ti 和 44Ti 中发现了 Alpha 聚类
52Ti，但观察到在 48Ti 中发生分解。讨论了这些结果的含义。
A novel technique has been developed, making use of the continuous wavelet transform to identify
α-clustered states from resonant scattering measurements in regions of high nuclear state density.
This technique expedites the investigation of α-clustering in medium mass and heavy nuclei, where
the role that α-clustering plays in the structure of the nucleus is poorly understood. Here we report
the application of this technique to measurements of the 4He(40,44,48Ca,α) resonant reactions, leading
to an assessment of the α-cluster structure of 44,48,52Ti. Alpha-clustering was identified in 44Ti and
52Ti, but was observed to break down in 48Ti. The implications of these results are discussed.
