Abstract

A search for the alpha + He-6 decay of Be-10 has been performed using the Li2O(O-18, alpha He-6) 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 O-16(O-18, alpha He-6)(24) Mg reaction was obtained, the cross-section being determined ass <1.9 mu b and <3.9 mu b at 80 and 100 MeV, respectively. The alpha + N-15 decay of F-19 was observed via the Li-7(O-18, alpha N-15)He-6 reaction. For the 19F excitation energy and centre-of-mass scattering angle ranges covered, the cross-sections are sigma = (31.7 +/- 6.6) mu b at 80 MeV and (31.8 +/- 6.6) mu b at 100 MeV.
