⁶H has been reported in the ⁷Li (⁷Li , ⁸B )⁶H reaction at E(⁷Li ) = 82 MeV (84AL1F, 85AL1G) [σ(θ) ~ 60 nb/sr at θ = 10°] and in the ⁹Be(¹¹B, ¹⁴O)⁶H reaction at E(¹¹B) = 88 MeV (86BE35) [σ(θ) ~ 16 nb/sr at θ ~ 8°]. ⁶H is unstable with respect to breakup into ³H + 3n by 2.7 ± 0.4 MeV, Γ = 1.8 ± 0.5 MeV (84AL1F), 2.6 ± 0.5 MeV, Γ = 1.3 ± 0.5 MeV (86BE35). We adopt 2.7 ± 0.3 MeV, Γ = 1.6 ± 0.4 MeV. See also (87BO40). The atomic mass excess of ⁶H using the (88WA18) masses for ³H and n, is then 41.9 ± 0.3 MeV. However, there is no evidence for the formation of ⁶H in the ⁶Li (π^- , π⁺) reaction at E_π^- = 220 MeV (87SE1C, 88SE1C; prelim.). The ground state of ⁶H is calculated to have J^π = 2^- . Excited states are predicted at 1.78, 2.80 and 4.79 MeV with J^π = 1^- , 0^- and 1⁺ [(0 + 1)h-bar ω model space] (85PO10) [see also for (0 + 2)h-bar ω calculations]. See also (86BE44, 87GO1Z), (83PO1D, 84AJ01, 86FL1A, 87AJ1A, 87PE1C, 88HA1I) and (87HA40, 87KU1F; theor.).
