Abstract
An excited superdeformed (SD) band has been observed in Hg-192 With th e EUROGAM spectrometer. It is interpreted as a two quasi-neutron excit ation in the Hg-192 SD nucleus. Nuclear level lifetimes have been meas ured using the Doppler-shift attenuation method. An average transition quadrupole moment of 19.5 +/- 1.5 b has been obtained which is simila r to the value measured in the yrast SD band. These results indicate t hat the deformation in the Hg-192 SD nucleus is stable despite changes in the occupancy of high-N orbitals.
