The ⁷Li(d, aa)n reaction induced by deuterons of an incident energy of 7 MeV has been used to excite the ⁸Be nucleus in the region of excitation energy E_x of about 20 MeV. Each of the obtained aa coincidence spectra was fitted by an incoherent sum of the J^p=2⁺ and 0⁺, T=0 ⁸Be levels at E_x=20.1 and 20.2 MeV, respectively. The results show that the experimental data are well fitted when the G values deduced for these levels are 0.90 and 0.70 MeV, respectively.
