Measured Ground-State Γ_cm(T_1/2) for ¹⁸B

Adopted value: < 26 ns (2003AU02)

Measured Mass Excess for ¹⁸B

Adopted value: 51852 ± 170 keV † (2010SP02)

^† value and uncertainty derived from ¹⁸B unbound by < 10 keV and ΔM(¹⁷B) = 43771 keV 170 and ΔM(n) = 8071. Assumes ¹⁷B is populated in its ground state.

Neutron Unbound

1984MU27: Not observed in fragmentation of ⁵⁶Fe on ⁹Be.

2010SP02: ⁹Be(¹⁹C, ¹⁸B → ¹⁷B + n), unbound resonance observed at E(¹⁷B + n)_rel < 10 keV.
