“…The intensity present in addition to the five visible peaks does not constitute background in the usual sense of the term 1 Cf. footnote to 6 Li were easily removed by gating on the corresponding peak in the d + α relative energy spectrum). Nonetheless, we shall refer to these broad structures as "background" when we discuss their contribution to the Dalitz plots displayed in Fig.…”

The reaction 3 He + 11 B → d + 12 C * has been used to populate resonances in 12 C up to an excitation energy of 15 MeV. The subsequent breakup to three α particles has been measured in complete kinematics. Dalitz plots are used to visualize and analyze the data. The Dalitz plot intensity distribution exhibits zero points characteristic of the total spin and parity of the 3α system allowing us to determine the spin and parity of a state in 12 C at 13.35 MeV whose quantum numbers were hitherto not well established. The Dalitz plot intensity distributions of the 2 − state at 11.83 MeV and the 1 + state at 12.71 MeV are compared with the predictions of a recent three-body calculation as well as with simpler models. All are able to reproduce the gross structures seen in the Dalitz plot, but none give an accurate description of the detailed profile of the distributions.

“…A number of experimental studies of the 3α breakup exist in the literature, see, e.g., Refs. [3][4][5][6][7][8] to analyze the data. The intensity distribution was compared with the predictions of the sequential and the democratic model, see Sec.…”
