Abstract
The h.f.s. of suitable lines excited in mercury extracted from several gold samples in different neutron fluxes has been photographed with a Fabry-Perot interferometer. As well as the strong lines due to Hg198, weak lines are also observed for Hg199 owing to the Au198 capturing a neutron before the β-decay. The branching ratio is[Formula: see text]Using the measured ratio of Hg199 to Hg198, τ = 2.69 days, and the neutron fluxes we have determined for the Au198 capture cross section, σ = (1.78 ± 0.10) × 104 barns.
