用80和100 MeV的Li 2 O（18 O，α 6 He）反应研究了10 Be的α+ 6 He衰变.两台硅-硅-碘化铯望远镜的阵列被用来同时探测分裂碎片。没有得到16 O（18 O，α 6 He）24 Mg反应的证据，在80和100 MeV下的截面分别为σ< 1.9 µB和< 3.9 µB。通过7 Li（18 O，α 15 N）6 He反应观察到19 F的α+ 15 N衰变.在19 F激发能和质心散射角范围内，80 MeV和100 MeV的截面分别为σ=（31.7±6.6）μB和（31.8±6.6）μB。
A search for the α+ 6 He decay of 10 Be has been performed using the Li 2 O (18 O, α 6 He) 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 16 O (18 O, α 6 He) 24 Mg reaction was obtained, the cross-section being determined as σ< 1.9 µb and< 3.9 µb at 80 and 100 MeV, respectively. The α+ 15 N decay of 19 F was observed via the 7 Li (18 O, α 15 N) 6 He reaction. For the 19 F excitation energy and centre-of-mass scattering angle ranges covered, the cross-sections are σ=(31.7±6.6) µb at 80 MeV and (31.8±6.6) µb at 100 MeV.
