Limit to high-spin isomeric fission
The possibility that high-spin isomers in heavy nuclei might undergo fission has been investigated experimentally. The partial fission lifetime of the 34 μs, I = 34 isomer in 212Fr is found to be at least one hou...

Superdeformed bands and ‘shears’ bands in 197Pb and 198Pb
Excited states in 197Pb and 198Pb, produced in the 186W (18O,xn) reaction, were studied using the EUROGAM phase 2 γ ray spectrometer array. Two new superdeformed bands have been observed in 197Pb, and the existen...

LEMS: application of the method to study the static quadrupole moment of the isomer in 179W
The method of the level mixing spectroscopy (LEMS) was applied for the first time for the study of the static quadrupole moments of high-K isomers in the A ≈ 180 mass region. Results from a preliminary experiment...

Transient field measurements of first-excited stateg-factors in188,190,192Os
Transient-field precessions were measured simultaneously for the 21 + states of188,190,192Os as ions of these nuclei traversed a thin polarized iron foil. In contrast with most earlier measurements, the relative ...

High spin states in129Ba
The high spin structure of the nucleus129Ba has been investigated using a18O induced reaction. The known bands could be followed up to a maximum spin (55/2) ħ. Some 56 states and 78 transitions could be placed in...

Disparity in transient field characteristics for Au ions traversing Fe and Gd hosts through measurements ofg-factors in197Au
Transient field precessions were measured for levels in the nuclides of182,184,186W and197Au as their ions simultaneously traversed polarized Fe and Gd hosts. Consistent sets of gyromagnetic ratios were inferred ...
