Nuclear Spins of the Isomers Hg191m-185m Determined by On-Line Quantum-Beat Spectroscopy Academic Article uri icon


  • The nuclear spins of the very neutron-deficient Hg191m-185m isomers were measured on line at the mass separator ISO LIDE at CERN using pulsed-laser excitation and observation of the time-resolved quantum beats from selected hyperfine-structure states. The spins of these isomers are with I=132 equal to those of the long-lived isomers Hg199m-193m already known. The persistence of this spin value for eight isomers is explained by the model of rotation-aligned coupling. 1979 The American Physical Society.
