5Be (1988AJ01)(See the Isobar Diagram for 5Be)
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(0) 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 Ex = 21.4 MeV: see (1979AJ01).
