5H (1988AJ01)The 9Be(11B, 15O) reaction at E(11B) = 52 - 76 MeV shows no evidence for the formation of 5H (1986BE35, 1987BO40). For the earlier work see (1984AJ01). See also (1987KO47, 1988SEZJ). There is some evidence for the formation of a very broad (8 ± 3 MeV) state of 5H at Ex = 7.4 ± 0.7 MeV in the 9Be(π-, pt) reaction (1987GO25). 5H is calculated to have Jπ = 1/2+, to be unstable with respect to two neutron emission and to have excited states at Ex = 2.44, 4.29 and 7.39 MeV with Jπ = 5/2+, 3/2+, and 3/2+ [(0 + 1)ℏω model space], and at Ex = 2.85, 3.46 and 6.02 MeV with Jπ = 3/2+, 5/2+ and 3/2+ [(0 + 2)ℏω model space] (1985PO10). See also (1982SM09, 1986BE44, 1987PE1C) and (1983ANZQ; theor.).
