This setup has very good timing response. Its rising time is just 8 ns. By using β-γ coincident technique, the intensities of γ lines following electron capture from neutrondeficient nuclides are strongly suppressed, but the detecting efficiency to the γ lines following 100% β^- decay of neutron-rich mercury nuclides arrives highly to 60%.
