Abstract:
Neutron deficient mercury isotopes were produced in the reaction 36Ar + 144Sm using bombarding energies of 180–230 MeV. Fusion products were separated in-flight from the primary beam using a gas-filled recoil separator. An alpha line with the alpha particle energy and half-life of (7069±11) keV and (2.1?0.7+1.8) ms, respectively, was assigned to the new mercury isotope 174Hg.
