Abstract
The presence of Delta I=2 staggering in the three known superdeformed (SD) bands of Hg-194 has been reexamined in a new experiment with Gamm asphere. A relative precision of better than 60 eV was achieved for mo st transition energies. Staggering plots were extracted and their stat istical significance was analyzed. No clear evidence was found for an extended regular Delta I=2 staggering in the three SD bands of Hg-194. However, statistically significant deviations from a smooth reference were observed in the two excited SD bands. Different scenarios are di scussed but no firm conclusion about the origin of the observed deviat ions can be drawn.
