Search for the α + ⁶He decay of ¹⁰Be via the ¹⁶O(¹⁸O, ¹⁰Be*)²⁴Mg reaction

A search for the α + ⁶He decay of ¹⁰Be has been performed using the Li₂O(¹⁸O,α⁶He) reaction at 80 and 100 MeV. An array of two Si-Si-CsI telescopes was used for the coincident detection of the breakup fragments. No evidence for the ¹⁶O(¹⁸O,α⁶He)²⁴ Mg reaction was obtained, the cross-section being determined as σ< 1.9 νb and <3.9 νb at 80 and 100 MeV, respectively. The α + ¹⁵N decay of ¹⁹F was observed via the ⁷Li(¹⁸O, α¹⁵N)⁶He reaction. For the ¹⁹F excitation energy and centre-of-mass scattering angle ranges covered, the cross-sections are σ = (31.7 6.6) νb at 80 MeV and (31.8 6.6) νb at 100 MeV.
