18B

Ground-State Decay Evaluated Data



Measured Ground-State Γcm(T1/2) 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.
