At E(⁹Be) = 121 MeV, ¹⁰Li has been observed in the ⁹Be(⁹Be, ⁸B)¹⁰Li reaction with a differential cross section (c.m.) of ≈ 30 nb/sr at θ = 14° (lab): Q₀ = -34.06 ± 0.25 MeV, and the atomic mass excess of ¹⁰Li is 33.83 ± 0.25 MeV if the group observed (Γ ≈ 1.2 ± 0.3 MeV) corresponds to the ground state. ¹⁰Li_g.s. would the be unbound with respect to breakup into ⁹Li + n by 0.80 ± 0.25 MeV (1975WI26). However (1979AB11, 1980AB16), on the basis of the possible location of the first T = 2 state in ¹⁰Be (see reaction 2) with J^π = 2^-, suggest that (1975WI26) have observed an excited state of ¹⁰Li, with J^π = 1⁺. See also (1979AJ01) and (1979BO22, 1980MA1Z, 1981AV02, 1981WA1J, 1982NG01; theor.).
