Nuclear spins of the isomers /sup 191m-185m/Hg determined by on-line quantum-beat spectroscopy

The nuclear spins of the very neutron-deficient /sup 191m-185m/Hg isomers were measured on line at the mass separator ISOLIDE 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=13/2...

Descripción
Sumario:The nuclear spins of the very neutron-deficient /sup 191m-185m/Hg isomers were measured on line at the mass separator ISOLIDE 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=13/2 equal to those of the long-lived isomers /sup 199m-193m/Hg already known. The persistence of this spin value for eight isomers is explained by the model of rotation-aligned coupling. (12 refs).
