The ⁹Be(¹¹B, ¹⁵O) reaction at E(¹¹B) = 52 - 76 MeV shows no evidence for the formation of ⁵H (86BE35, 87BO40). For the earlier work see (84AJ01). See also (87KO47, 88SE1C). There is some evidence for the formation of a very broad (8 ± 3 MeV) state of ⁵H at E_x = 7.4 ± 0.7 MeV in the ⁹Be(π^-, pt) reaction (87GO25). ⁵H is calculated to have J^π = 1/2⁺, to be unstable with respect to two neutron emission and to have excited states at E_x = 2.44, 4.29 and 7.39 MeV with J^π = 5/2⁺, 3/2⁺, and 3/2⁺ [(0 + 1)h-bar ω model space], and at E_x = 2.85, 3.46 and 6.02 MeV with J^π = 3/2⁺, 5/2⁺ and 3/2⁺ [(0 + 2)h-bar ω model space] (85PO10). See also (82SM1B, 86BE44, 87PE1C) and (83ANZQ; theor.).
