High spin states in the isotope 194Hg were populated using the 150Nd (48Ca,4n) reaction at a beam energy of 213 MeV. A sequence of dip ole transitions has been observed above 8 MeV excitation energy. Cross-over transitions have also been identified.

High spin states in the isotope194Hg were populated using the150Nd (48Ca,4n) reaction at a beam energy of 213 MeV. The analysis ofγ-γ coincidences has revealed two new structures at excitation energies above 6 MeV and at moderate spin. The two stru

Precise level lifetimes have been measured for various superdeformed bands in Gd-148,Gd-149 and Dy-152 with the Doppler-shift attenuation method From the derived quadrupole moments, Q(0), we find large differences in deformation between the yrast ban

The Eurogam I gamma -ray array has been used to search for the linking transitions between the superdeformed (SD) and normal deformed states in 152Dy. Triple gamma -ray coincidence data were analysed by employing the technique of summation of discret

A new superdeformed band is reported in 193Hg which has properties that are consistent with it being based on the unfavoured N = 7 (π, α) = (−, +12) intruder orbital. The signature splitting at hω = 200 keV of this intruder orbital and its favou

An excited superdeformed (SD) band in 150 Gd is associated with a two-particle-two-hole proton excitation and provides the first evidence for collective proton pair excitations in a SD nucleus. This band is seen to exhibit a discontinuity in the γ-r

Lifetimes of states in four of the oblate dipole bands in $^{197,198}\mathrm{Pb}$ have been measured with the recoil distance technique. Using all the available data on lifetimes and branching ratios, and assuming pure magnetic dipole transitions, we

The moment of inertia of the yrast superdeformed band in [sup 149]Gd exhibits an unexpected bifurcation at high rotational frequency. States differing by four units of angular momentum show an energy shift of about 60 eV. This indicates the remnant o

Dipole transitions linking signature partner superdeformed bands in 193Hg have been observed. Measurements of the photon decay branching ratios, taken together with the average superdeformed quadrupole moment measured in neighboring nuclei, enable th
