  The absolute branching ratio of the beta-delayed gamma-ray emission of N18
was measured, providing absolute normalization of the previous work by Olness
et al. [J.W. Olness et al., Nuc. Phys. A373, 13 (1982)] who measured the
relative branching ratios for the individual gamma-rays. We find the total
absolute branching ratio for beta-delayed gamma emission of N18 to be 76.7 +/-
7.2(stat) +/- 5.8(norm)%. A combination of other results suggests a value
consistent with our result, but smaller than that calculated by Millener as
quoted in Olness et al.
