Test of Δ I=2 staggering in superdeformed 194Hg
Abstract
The observation of a Δ I=2 staggering in several superdeformed (SD) bands is one of the most exciting new findings in nuclear structure physics. Several theoretical approaches have attempted to explain this staggering but have not succeeded. Also the experimental results are not beyond doubt and their confirmation is urgently needed. We report here on a new high statistics experiment on ^194Hg aiming to verify the previously reported^1) staggering in its three SD bands. The reaction ^150Nd(^48Ca,4n) at a beam energy of 202 MeV was used to populate SD states in ^194Hg. This new measurement with Gammasphere results in an unprecedented precision of the SD transition energies. We will show that the previous report can be partly confirmed.
