title: Neutron capture cross sections of 194Hg and the decays of 195Hg.
abstract: The thermal cross section and resonance integral have been determined for radiative neutron capture by radioactive (194)Hg by observing the γ rays emitted in the decay of (195)Hg. Captures leading to the low-spin isomer of (195)Hg give σ=877 b and I=10,270 b, while captures leading to the high-spin isomer give σ=49 b and I=608 b. Energies and intensities of the γ rays emitted in the decays of (195)Hg produced by neutron capture have been obtained with increased precision relative to previous studies with sources produced by other reactions, leading to correspondingly improved values for β-decay branching intensities and energy levels in (195)Au. New values for the half-lives of (195g)Hg and (195m)Hg are also reported.
