Absolute Branching Ratio of Beta-Delayed Gamma-Ray Emission of N18
Abstract
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.
