Abstract

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