Signatures of α-clustering in 12C and 13C

We study the cluster structure of 12C and 13C in the framework of the cluster shell model. Simple relations are derived for ratios of longitudinal form factors as well as transition probabilities. It is shown that the available experimental data for 12C and 13C can be well described by a triangular structure with D3h and D'3h symmetry, respectively. & COPY; 2023 The Author(s).

Automated summary

The cluster structure of 12C and 13C is investigated using the cluster shell model. Simple relationships for ratios of longitudinal form factors and transition probabilities are derived. It is demonstrated that the experimental data for 12C and 13C can be well explained by a triangular structure with D3h and D'3h symmetries, respectively.
