At E(⁹Be) = 121 MeV, the ground state of 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 &177; 0.25 MeV, and the atomic mass excess of ¹⁰Li is 33.83 &177; 0.25 MeV. The width of the ground state is ~ 1.2 &177; 0.3 MeV. ¹⁰Li_g.s. is unbound with respect to breakup into ⁹Li + n by 0.80 &177; 0.25 MeV (WI75G).
