“…While particle unbound states in 10 Be usually decay by neutron emission, the 10.15-MeV state has only been observed to decay by α emission [6,7,12,13]. It has a very large α width comparable to the Wigner limit [7], and it decays both to the 0 + ground state and the 2 + first-excited state in 6 He [13]. One may reasonably assume similar decay properties for the analog state in 10 B, i.e., the decay should be dominated by α emission to the 0 + and 2 + , T = 1 states in 6 Li located at 3.56 and 5.37 MeV, respectively.…”
