The absence of any group structure in the neutron spectrum in the reaction ³He(³He, n)⁵Be at E(³He) = 18.0 to 26.0 MeV indicates that ⁵Be_g.s is at least 4.2 MeV unstable with respect to ³He + 2p [(M - A) > 33.7 MeV]. With Coulomb corrections adjusted to match the 16.7 MeV states of ⁵He - ⁵Li, this observation places the first T = 3/2 level in these nuclei above E_x = 21.4 MeV: see (1979AJ01).
