Abstract
We briefly review recent progress in clarifying the role of α clustering in12C and discuss how experimental studies of the α + α + α breakup of excited states in12C contribute towards this goal. Finally, we show preliminary data from ongoing experimental studies of the p +11B →α + α + α reaction at the 5 MV Van dee Graaff accelerator at Aarhus University.
Highlights
To what extent can we think of the 12C nucleus as composed of three closely spaced α particles? Recent years have witnessed significant progress towards answering this nearly century-old question
The microscopic calculations readily predict excitation spectra and transition strengths which can be checked against experimental data, but since the calculations all employ some type of bound-state approximation they do not make any predictions concerning the couplings to particle channels, such as α + α + α which incidentally is the only particle-decay channel open at low excitation energies
Computational schemes have been develop to solve the α+α+α three-body problem in the continuum, and these schemes have been employed to determine the final-state momentum distribution of the 12C∗ → α + α + α breakup process [5, 6] as well as the cross section of the α + α + α → 12C+γ fusion process [7, 8, 9]
