¹⁴Be has been observed in the 4.8 GeV proton bombardment of uranium [see (1976AJ04)], in the bombardment of ²³²Th by 145 MeV ¹⁵N ions (1982OG02; forward differential cross section is 4 × 10^-5 mb/sr) and in the ¹⁴C(π^-, π⁺)¹⁴Be reaction (1984GI09; E_π^- = 164 MeV, θ = 5°). It has not been observed in the ⁴⁸Ca(¹⁴C, ¹⁴Be)⁴⁸Ti reaction (E(¹⁴C) = 87.4 MeV, θ = 4° - 8°) (1981NAZQ). A group in the (π^-, π⁺) reaction is observed at Q = -37.08 ± 0.13 MeV [(Value quoted by (1984GI09) + 2m_ec².)] with a cross section of 0.73 ± 0.19 μb/sr (1984GI09). If this is the ground-state group, the atomic mass excess is 40.10 ± 0.13 MeV. ¹⁴Be is then bound by 2.97 and 1.12 MeV, respectively, with respect to decay into ¹³Be + n and ¹²Be + 2n. See also (1984EP1A) and (1981KI04, 1981SE06, 1983ANZQ, 1985WI1B; theor.).
