Abstract:
The 2α + 2p breakup and structure of the only known Brunnian nucleus, ¹⁰C, has been studied at 33.3 MeV/nucleon. Detection of the 2α + 2p breakup fragments using a highly segmented Si-Si-Si-CsI detector array has allowed the ¹⁰C \rightarrow ⁹B + p, ⁹B \rightarrow ⁸Be + p, ⁸Be \rightarrow α + α and ¹⁰C \rightarrow ⁶Be + α, ⁶Be \rightarrow ⁵Li + p, ⁵Li \rightarrow α + p decay channels to be reconstructed. Proton emission was seen to be favoured. Resonant breakup was observed from excited states at Ex = 4.20, 5.31 and 6.74 MeV. The previously unobserved state at 4.20 MeV may correspond to a 0⁺ α+2p+α cluster structure.
